Many people treat their computers--both desktops and laptops--as if they were household appliances. They take a "set it and forget it" kind of approach. They may take very little care in terms of regular maintenance and taking the time to clean a computer properly can often get neglected. Just as other household appliances should be cleaned now and then, the same can be said about a computer.
Many people treat their computers--both desktops and
laptops--as if they were household appliances. They take a "set it and
forget it" kind of approach. They may take very little care in terms of
regular maintenance and taking the time to clean a computer properly can often
get neglected. Just as other household appliances should be cleaned now and
then, the same can be said about a computer.
Clean the Exterior Case
The outside of a desktop tower generally
doesn't get too dirty, but the top and sides can start to accumulate a fair bit
of dust over time and this can become even more problematic around the various
ports and vents. While a regular feather duster might do the trick, it could
also leave little feathers and other debris on the computer itself.
Instead, a simple microfiber cleaning cloth is a better solution. Just give the surface of the computer case a good wipe and it should clean off the majority of the dust. The portions of the case that do not have any ports or vents can be cleaned with a little bit of water, but using isopropyl rubbing alcohol can be even better for removing grease stains. The outside of a laptop can be handled in much the same way.
Computer Screens and Monitors
Just like the exterior case of a desktop
computer, the accompanying computer monitors typically don't get all that
dirty. They can suffer from a fair bit of dust and, with the growing popularity
of touchscreens, they can also be prone to a lot of fingerprints and smudges.
Products
to Use
One of the most important tips for cleaning a computer screen is to be extra careful with the cleaning products that you use. Certain chemicals, like those containing acetone, can be very damaging to the screen. Instead, use a gentle microfiber cloth for a dry wipe and if additional cleaning is needed, a very small amount of isopropyl alcohol can be applied with gentle, even strokes.
Purchase a Screen Protector
In the case of laptops and convertible tablets, screen protectors are available that are effectively the same kind of product as those designed for smartphones.
Internal Components
Even though the internals of a computer are enclosed inside of a case, they can also get quite dusty and dirty over time. This is mostly because of the air being passed through the system for the purpose of cooling and the accumulated dust can be detrimental to performance and can cause serious hardware problems. Too much dust trapped in the vents and fans can lead to overheating. Free software like HWMonitor from CPUID can help to track and monitor the internal temperatures of the various components inside your computer.
Desktops
To clean a desktop computer, you will need
to open up the case. Depending on the case that you have, this could be as
simple as removing a few screws or it could be more complex. It may or may not
be necessary to unplug the various cables connected in the back.
With the computer turned off and the internals exposed, use a compressed air duster to remove the dust from inside the system. Cans of compressed air can be purchased from several retailers. For greater air pressure, electric air dusters are also available. Have a good look around every nook and cranny, clearing out the dust from all the fans, intakes, exhausts and vents.
Notebooks and Laptops
Opening
up the casing on a notebook computer may be more difficult and it may be less
necessary. Use the same compressed air duster to clear out the intake and
exhaust vents visible from the outside.
Keyboard and Mouse
Keyboard and mouse dust - Flip the keyboard upside down and use the same can of compressed air to clear out all the dust and small bits of debris between the keys. The same can be done with any nooks and crannies on the computer mouse.
Fingertip grease - Fingertips have a natural oil to them and this can build up into greasy stains on keyboards and mice over time. Use very small amounts of isopropyl or ethyl alcohol on a soft microfiber cloth to help remove some of this grease. This can also be useful for helping with sticky keys.
Grime - If there is grime stuck between or underneath the keys, the individual key caps can usually be gently removed from most mechanical keyboards. It can be more difficult or potentially harmful to remove the individual keys on a membrane-based keyboard. Check accordingly.
Note
that the oils are absorbed into the plastic of the keys and on the mouse, so
you may not be able to get them completely clean.
Other Desktop Accessories
It is important to keep the rest of your
computer accessories clean as well. External hard drives, particularly larger
units, can also have intake and exhaust vents the same way that a desktop tower
does. It is not recommended to take these products apart, but you can use the
cans of compressed air to clear out some of the dust.
The
surfaces of computer speakers, mouse pads, webcams and other peripherals can be
similarly cleaned with microfiber cloths and rubbing alcohol.
A Clean Computer Is a Happy Computer
Just as it is a wise decision to clean out
the inside of a microwave oven on a regular basis, it is an even better idea to
clean all the components of a computer from time to time. This is for sanitary
and cosmetic reasons, and to help the computer operate at its best.
Printer ink can be a significant cost for both business and home computer users. The average cost of printer inkranges from about $120 to $840 per year. While printing is often a necessity, there are things you can do to reduce the amount of money you spend on ink.
Use
an Ink Subscription
While
purchasing off-the-shelf original equipment manufacturer (OEM) cartridges is
generally the most expensive way to buy replacement ink, many printer
manufacturers have introduced subscription options designed to help people save
money and time.
Hewlett Packard
Hewlett Packard (HP) offers an Instant Ink program where your printer automatically sends a message letting the company know you're getting low on ink so it gets sent before you run out. Simply choose a plan, ranging from $3 to $10 per month based on how many pages you print monthly. Shipping costs are included.
Canon
Canon's Recurring Ink & Toner program allows you to pre-schedule orders based on how often you typically need to buy ink or toner. Set up automatic deliveries in four-week increments from every four weeks to every 24 weeks.
Brother
Similar to the HP Instant Ink program, Brother's Ink & Toner Auto-Fulfillment Program uses technology to automatically detect when you need ink. You'll pay the cost of the ink cartridge for your printer plus shipping and handling.
Buy Compatible Cartridges
OEM ink is not the only new cartridge purchase option. Compatible cartridges are available for most printer models from highly recommended e-commerce retailers.
123InkJets.com: This retailer is described in reviews as "a convenient place to shop," thanks to their "large ink inventory and modern payment options." The store's website promises savings of up to 75 percent, a one-year guarantee, and free shipping on orders exceeding $55.
4inkjets: With a "Best Overall" rating from TopTenReviews, 4inkjets carries more popular cartridges than most other stores, promises to ship orders out the same day, and allows returns up to two years after purchase.
InkCartridges: Known for their free shipping on orders to the contiguous United States, this retailer also offers discounts for bulk orders.
Give Recycled Cartridges a Try
Bill Swanson, former CEO of Cartridge World North America, explains the price difference between recycled and new cartridges: "It's because many components of a printer cartridge can be used again without sacrificing the quality of the cartridge." Swanson states that recycled cartridges can "save customers as much as 30 percent over competitors."
Quality Concerns
It's important to realize that not all recycled cartridges are the same. "As in any industry, there are a handful of companies selling inferior products." says Swanson.
Where To Buy Recycled Cartridges
Brick and mortar stores like Staples and online giants such as Amazon sell hundreds of different remanufactured or refilled cartridges for most of the popular printer brands.
Purchase Refill Kits
It is also possible to refill printer cartridges yourself, though it's important to consider what is really involved with this money-saving approach. Refill kits can save consumers up to 90 percent over buying new OEM cartridges. However, the savings might not always be worth the mess.
Refilled cartridges can spill out into the printer causing a mess and possible permanent damage. They also won't necessarily cancel "low ink" messages. In a review on The Simple Dollar, the user and colleagues deemed refill kits as acceptable as long as you're not "printing photographsor other documents that you intend to share or archive."
Make the Most of In-Store Refills
If you like the idea of refilling ink cartridges but you'd rather not deal with the mess, there a few in-store programs you may find helpful. For example, Fry's refills cartridges in the store for most major printer brands. Refill start as low as $7 and the store claims the service can result in up to a 65 percent savings on ink.
Use a Cartridge Return Program
Many stores offer opportunities for customers to earn rewards points or cash for trading in empty ink containers that can be recycled. Examples of these recycling programs include:
Office Max: Sign up for the OfficeMax Ink & Toner Recycling Program and begin earning your choice of rewards or cash, with payouts occurring after your balance reaches $50.
Office Depot: Receive $2 Office Depot Rewards for each recyclable cartridge that you turn in, up to a maximum of 10 per month.
Staples: When you recycle your cartridges with Staples, you'll receive $2 in Staples Rewards per item, with a monthly limit of 10. Rewards can be used to purchase any items you need from the store.
Quill: You can earn $2 in Quill Cash for up to 10 recyclable cartridges per month, with the value applicable to purchases from the online retailer.
Ten Additional Ink Savings Tips
While finding good deals on replacement ink is critical for getting the most out of your printing budget, it is not the only way you can save money.
Printer selection: Swanson recommends "buying efficient printer models" as a way of controlling ink expenditures.
Software solutions: Use free software programs to reduce the number of pages printed and ink used.
Font size: Instead of using larger fonts, try 10-point type for most documents, something that can save both ink and paper.
Font selection: When choosing a font, consider how much ink it uses, opting for those with thin lines rather than heavy ones. A recent study found that Garamond uses the least ink.
Use Ecofont:Ecofont is a collection of perforated fonts to reduce ink consumption. A single user-license costs around $8 per month.
Quality settings: Adjust your default printer quality setting to low so that you use the least amount of ink possible for day-to-day printing. Manually adjust for high quality printing when needed.
Print specific sections: Limit printing to specific sections of documents or web pages that you need to print to reduce ink usage.
Regular printing: Ink cartridges that sit for too long can dry out and become unusable. To keep this from happening, those who print only rarely should make it a point to print something at least once a week.
Shake the cartridge: When you notice the print quality start to diminish, don't run out and buy a new cartridge. Removing it and shaking it well before replacing can re-distribute the ink, extending its useful life.
Rely on mobile devices: It's wasteful for smartphone users to print maps and directions. If you have a phone with GPS, it can find directions for you.
Make the Most of Your Ink Dollars
No matter which of these options you
choose, it's easy to see that there are plenty of ways you can get more for
your money. Try a few tips at a time to see what options are best for you.
Whether you are doing some basic house cleaning or your television screen got dirty somehow, there are different methods to clean it depending on if you have a flat screen or a CRT (cathode ray tube). Therefore, it is important to differentiate between the two before scrubbing off those smudges.
Cleaning
Flat Screen Televisions
All newer televisions on the market are flat screens. According to manufacturer's warnings through brands like LG and Panasonic, you must be careful when cleaning your television because of the screen's anti-glare coating. Using harsh chemicals or alcohol breaks down this coating and hurts the flat screen. This is true for all types of flat screens including LED, LCD,plasma, and other types.
What You Need
Microfiber cloth
Mild dish soap (any will do) or
HDTV/flat screen cleaner
Water
Optional duster
Steps:
Unplug the television before cleaning the screen, especially if you are using a damp or wet cloth.
To remove the dust from the screen, use the microfiber cloth or a feather duster. If your screen isn't excessively dirt or doesn't have screaks or smudges, this might be all you need to do.
If you TV is heavily soiled or needs a more thorough cleaning, you can try a few different methods.
Some manufacturers recommend wetting your microfiber towel and squeezing out the excessive water. Use the damp cloth to remove any smudges or stains. Using a clean dry cloth, buff the surface gently to avoid streaks.
If water alone won't cut it, use soap and water. Add a small squirt of dish soap to a couple cups of warm water, dunk the cloth in the mixture and wring it out. Then use the cloth to gently remove any residue or debris. Rub with a dry cloth to remove any streaks and buff.
If all else fails, use a flat screen TV cleaner. Add a couple squirts of the cleaner to the cloth and gently clean the screen.
Keep in mind when using a cleaner to double check with your television's manual to ensure the manufacture lists the cleaner's ingredients as safe for that screen.
Cleaning CRT TVs
Cleaning
a non-flat screen television or CRT TV requires a different approach because
the screens on these televisions are typically made of glass.
Materials
Microfiber cloth/towel
Glass cleaner/alcohol
Steps
Unplug the television if you will be using a damp cloth.
Wipe the screen with a dry cloth to remove any dust or stuck on particles before using cleaners.
Dampen your cloth with glass cleaner or a 50/50 mix of rubbing alcohol and water.
Wipe the television screen with the damp cloth. Use gentle circular motions to scrub any excessively dirty areas. This loosens any stuck-on particles.
Using a clean, dry cloth, buff the screen using a circular motion. This will help to avoid those annoying streaks.
Spot Cleaning
If you
need to remove a smudge or dirt in one area instead of cleaning your entire
screen, follow the same steps for your type of television. However, rather than
wiping down the entire screen, focus only on the soiled area. Remember to dust
the entire screen first to ensure you don't have just one clean area.
Words of Caution
When cleaning your screen:
Never use excess water.
Don't pray anything directly on
the screen. This could not only damage the screen but other components as well.
Never use a rough or abrasive
cloth for cleaning the screen. This could scratch the screen.
Always double check ingredients
if you are using a cleaner on your flat screen. This will ensure you don't harm
the screen.
Perfect Viewing
Over time, your television will get dirty and if you have little ones or a touchscreen, it can get really dirty. Therefore, it is important to know how to clean your specific screen so you can avoid damaging it. When in doubt, just use water. Now you can add this to your house cleaningroutine list.

Given their popularity and value it is a good idea to learn how to clean LCD screens without causing major damage to them.
About
LCD Screens
Liquid Crystal Display (LCD) screens, also
known as flat panel monitors, were once the wave of the future. LCD screens are
standard features on everything from laptop computers and cell phones to
televisions, digital cameras and calculators. LCD displays are made of a layer
of crystal solution that is sandwiched between two sheets of flexible
polarizing material.
Unlike old-fashioned glass monitors, LCD screens are much more delicate. There are mazes of circuitry and electrical components that reside inside a LCD monitor, which are very sensitive to moisture. As such, it is critical that liquid cleaners never come into contact with the inner mechanisms of LCD screens, especially since the display is created in large part by various voltages of electricity being sent to cells of liquid crystal.
How to Clean LCD Screens Properly
The surface of LCD screens is made from
soft plastic materials which are extremely vulnerable to scratches. What's
more, most large HDTVs are coated with a special anti-glare substrate, which
can be damaged if you don't learn how to clean LCD screens properly.
The following tips will help you prevent damaging your LCD screens during the cleaning process:
Power Down
Before
you start cleaning your LCD screen, be sure to turn it off. Never clean while
the monitor is on. Rather, shut off the power to the LCD screen and allow it to
cool down prior to cleaning it. A warm surface will evaporate cleaning
solutions before you have a chance to wipe the screen and you will be left with
large streaks.
Use Soft Cloths
While
it may be tempting to do so, never use Kleenex, paper towels, or other coarse
rags to clean LCD screens. The aforementioned materials may contain abrasives
that can damage the delicate surfaces or protective surface coatings of LCD
screens. In addition, materials, such as facial tissue can be quite dusty and
will leave lint on your screen during the cleaning process. The best materials
to clean LCD screens with are lint-free microfiber towels, clean cotton rags,
or disposable dust cloths.
Air Method
For
daily cleanings, use canned air to remove dust and debris from the edges or
corners of your LCD screen. Canned air can also be used as the first step in a
more thorough cleaning process. Simply apply the air to the surface of the
screen to remove large pieces of dust before giving your monitor a good wipe
down.
Avoid Liquid Cleaners
LCD screens and liquid cleaners do not mix well. Liquid cleaners that are designed specifically to clean LCD screens should only be used periodically. What's more, you should never use a cleaner that contains ketones, as they can destroy the screen's anti-glare coating. If you must use a liquid cleaner on a LCD screen be sure to spray it onto a clean cloth rather than applying it directly to the screen. You never want to run the risk of liquid cleaner seeping under the frame of the screen. Also, if you cannot afford to purchase low-impact LCD screen cleaning solution you can use diluted isopropyl alcohol in very small amounts to clean your monitor.
Be Gentle
LCD
screens are fragile and should be cleaned with gentle strokes. Never press on
the screen with your fingers or other objects, as excessive wiping pressure can
damage the monitor.
Size Matters
Size
matters when it comes to learning how to clean LCD screens. Smaller LCD
displays can typically be cleaned with a single wipe. However, large flat
screen TVs should be cleaned in sections. Attempting to clean the entire
surface of a huge HGTV screen can cause streaks and smudges. In addition, it
can damage the screen's protective coating. Your best bet when cleaning large
LCD screens is to work on half or a third of the screen, and then proceed on
with the rest when you are done with the first section.
Knowing how to clean a computer screen properly will help you extend the life of your monitor, save you money and preserve your vision.
Know Your Computer Screen
Before you dig under the sink for something to clean your monitor with, you need to determine the type of computer screen you have. Typically, computer monitors are placed in either of two categories: CRT or LCD.
Cathode Ray Tube (CRT) monitors are older models. They are traditionally larger and bulkier than their LCD counterparts. What's more, their screens are made of glass, which means they can be cleaned with commercial products made specifically for glass.
In contrast, Liquid Crystal Display (LCD) monitors contain multiple sheets of a non-glass polarizing material with a layer of liquid crystal solution in between. LCD monitors cannot and should not be cleaned in the same fashion as glass CRT monitors.
Tips on How to Clean a Computer Screen
Regardless of whether you own a CRT or LCD computer monitor, it is vital to be extra careful during the cleaning process. Monitors are fragile and must be treated delicately in order to preserve their features.
The following tips will help you take the stress out of learning how to clean a computer screen:
CRT
Windex or other commercial glass cleaners are recommended for removing dirt, dust and fingerprints from glass monitors that come with standard CRT computers. However, you should never spray a liquid glass cleaner directly on a monitor, as the solution could seep into the screen and damage the circuitry. To avoid harming your computer screen, simply spray some Windex onto a soft cloth or paper towel, and then gently wipe the glass monitor using even strokes.If your CRT computer screen is exceptionally grimy or contains a ton of dusty smudges, then you could opt to vacuum off larger dust particles. If you choose this option be sure to use a soft brush attachment on your vacuum prior to cleaning your glass computer monitor.
Other good cleaning materials for CRT monitors are microfiber towels dampened with a little water or dry disposable dusters, such as Swiffer Duster Cloths or Staples' Lint-Free Wipes, which offer nonabrasive cleaning.
LCD
You must be extremely careful when cleaning a LCD computer screen, as using the wrong type of cleaners could seriously damage your monitor. Never use a cleaner that contains acetone to remove dirt and debris from LCD monitors. Rather, it is best to dry clean a LCD screen with gentle microfiber cloths or a soft cotton rag. If the dry method does not completely clean the screen, you can add a touch of isopropyl alcohol to a soft cloth, and then wipe the screen using gentle, even strokes.
Additional Cleaning Tips
Working on a computer screen that is caked with layers of dirt, dust and debris can be hard on your eyes. In addition, allowing grime to build-up on your monitor may compromise the integrity of the machine and lessen its value over time. This is why it's important to learn how to clean a computer screen properly. However, before you tackle the task, you must first turn off the monitor. Never clean a computer screen while the machine is on. What's more, you shouldn't turn it on again until the screen is completely dry.
No matter how responsible or communicative your children are, ensuring their online activity is safe and healthy is no easy matter.
For parents, this is a challenge on many levels. What content
are children accessing? Which devices are they using to go online? What time of
day are they connecting and how long are they spending at different activities?
While modern devices come with their own parental controls,
these systems don’t speak to each other. Setting limits on access YouTube on a
console can mean that children simply migrate to a different screen once this
has been used up.
The Nintendo Switch may be leading the way with its ability
to report on what children are playing, but when these limits are used up kids
can simply move over to another console, such as an Xbox One or PlayStation 4.
That's where Circle with Disney comes in. It is a one-stop shop to control a family's internet usage at source. So here's everything you need to know about the cunning device, including how to set it up.
What is
Circle with Disney?
Circle with Disney is a physical box that wirelessly
connects to your home network to monitor, control and report on internet
activity.
It’s clever because it does this for all the devices you have
in the house and can assign each device to different user-specific limits.
Better still, like the Nintendo Switch’s parental controls, you control Circle
from an app on your smartphone and get messages directly when limits are
exceeded.
It can, therefore, enable control over specific devices in
the home, such as those used predominantly by your children, without impacting
on the internet abilities of parents' devices.
How does
Circle with Disney work?
Plugging in and setting up a Circle with Disney box is an
eye-opening experience. In a matter of days you can clearly see how long each
family member is spending at different online activities no matter which
devices they are using.
This information enables you to set up time limits for
particular activities - YouTube, Xbox or Pinterest for example - or to block
particular sites and services that are not appropriate. Some games can also be
specifically limited - like Roblox, which has been really helpful in our
family. Once the time is up for a particular user they get the message on their
devices and need to ask parents for an extension.
Along with time limits on apps and websites, Circle can also
specify bedtimes and off-times for each user. This is very useful for ensuring
your kids don’t stay up too late, or get delayed checking Instagram in the
morning before school.
Performance is good, with the system not slowing down the
performance of your internet connection and proving itself super stable. One
snag to date has been on the change from GMT to BST. Circle failed to update
its clock and so the time-specific limits were out by an hour. The guide
suggests that connecting a new user to the device with the new time is a
workaround but we couldn’t get this to work. Instead, we had to set the limits
back an hour in the app. This is likely to be resolved in the near future.
How to set up a Circle with Disney box
As with any new technology in the home, it’s
essential you set up your Circle with Disney box correctly. So here’s the
definitive guide for setting up Circle and reclaiming control of the devices
and online services in your household.
Step 1:
Unbox and plug in
Circle comes with simple instructions and is easy to set up.
Take it out the box, plug it in via any USB power port and then connect to it
via your smartphone or tablet.
Download the Circle app. Ensure this is the app called
"Circle Home", don't just search on app stores for "Circle"
as there are other, non-related apps called that.
Step 2:
Connect to your network
The Circle Home app will detect your Circle hardware. If it
doesn’t, press the button on top to reset it and turn it on. There should be a
green light if it is functioning correctly.
The app will then prompt you to connect to the Circle hardware via the Wi-Fi connection on your device. Once that is done you are ready to set up devices and users.
Step 3:
Set up users
The next step is to go through your devices identifying each
one, and naming them. This is particularly important if you have multiple
tablets or phones in the home as you need to know which is which. This should
also include games consoles, Smart TVs, family computers, as well as
smartphones and tablets.
With each device named you can set up user profiles for the
people in your family. Some time and planning is worthwhile here. You may want
to set up all the children’s devices in one "Kids" profile as this
ensures they don’t trade tablets and online time.
Alternatively, and this will depend on the age of your
children, you may want to have different restrictions, bed times and off
times for each of them. If this is the case you need to create their own
profiles.
The final consideration here is if you are going to connect
Circle to one of the rewards apps. This can grant them more online time for
completing household chores or performance at school. If this would be useful
you need to have separate profiles for each child to be able to apply rewards individually.
Step 4:
Check "Insights"
Once you have the basic settings established, it’s best to
let your family use their devices for a few days to see how it works. This will
provide valuable information on the "Insights" tab on how they are
using their online time.
This information can be used to set additional limits to the
apps and services that are appearing there as well as tweak limits on their
online time.
Step 5:
Set up "Off Time"
Once you have Circle set up as you want it, the Off Time
settings can add a useful extra layer of control. For example, in the morning
children will have plenty of their online allowance left but may be distracted
on devices rather than getting ready for school.
Setting an Off Time for the hour before they leave for school
is a convenient way to avoid this distraction and get them out the door on
time.
Step 7:
Notifications
Whenever a time limit is reached or new device enters the
home you are notified via a message on Circle. It’s worth ensuring these
messages are forwarded to smartwatches and other devices to give you an instant
heads up when something happens.
For example, when a child’s YouTube allowance for the day is
consumed you will receive a message before they realise the limit has been hit.
This enables parents to be one step ahead of children’s requests for more time.
Step 8.
Close loopholes
As the family gets used to having their online time mediated in this way there are inevitable loopholes that will emerge. Limiting a child from accessing YouTube on his or her iPad will naturally lead to them using the PC for this activity instead.
Ensuring you don’t have any devices unassigned to a user
enables you to limit activity across the whole home. It can also be a nice way
to ensure certain activities are enjoyed on screens in shared family spaces.
Step 9.
Guests and parents
While Circle will largely be used by parents to understand
and control access to online services by their children, it can also be useful
for adults in the home. Creating a parent user enables you to set limits to
using the phone before bed or while enjoying weekend time together.
When other children come to visit the family, it’s a good
idea to name their device and add it to a guests group. This not only ensures
you understand what they are doing online with friends but also notifies you
when any new devices enter the home.
Do we
recommend it?
Circle with Disney is unlike any other internet control
service we’ve used. While it is possible to achieve similar functionality if
you know how to dig into your router settings or customise complex user
profiles, Circle offers all this in a simple and well thought
out interface that anyone can set up.
Priced at £99 in the UK and $53 in the US currently, it’s not the cheapest way to control your family’s internet consumption but it does offer a lot of value. For parents, being so easy to set up, getting instant notifications and seeing their children’s online behaviour change overnight makes it worth its weight in gold.
