Dust, fingerprints, and unsightly scratches can make you uncomfortable using the monitor. In cleaning it, it is very important to use a gentle method, because the monitor is made with a type of plastic that can be easily scratched if cleaned with harsh chemicals. This article will show you how to clean your computer monitor without causing damage while removing scratches, if any.
Step
Part 1 of 2: Safely Cleaning the Monitor
Step 1. Turn off the monitor
Dust and dirt are easier to see when the monitor is turned off. You and your computer will be safer too.
- If you clean the monitor while the pixels are being shot, your screen could be damaged.
- Although the risk is small but you can get electrocuted if the monitor is cleaned while it is on.
Step 2. Clean the monitor frame
Spray Windex or another mild cleaning solution onto a clean cloth, then use it to wipe the casing around the screen.
- The monitor case is made of durable plastic, so you can rub it lightly to remove any adhering dirt.
- Do not spray cleaner directly on the case, as the droplets can hit the screen or drip into crevices and into the interior of the screen.
- Clean the bottom of the monitor, the buttons, and the back. Wrap the corner of the cloth around your finger or a toothpick to clean hard-to-reach crevices.
- If the monitor has a connecting cable to the CPU or power, unplug it and clean it.
Step 3. Wipe the monitor with a piece of soft clean cloth
Microfiber cloth is ideal for use. This type of antistatic fabric does not leave a lint residue on the screen and is also soft so it will not scratch the surface of the monitor. Wipe off visible dust and dirt using a cloth.
- Do not use towels, paper products or rough cloths to wipe the screen. All of these will leave behind lint and can scratch the screen.
- You can also use a disposable cleaning cloth, such as a Swiffer cloth.
- Do not press hard on the screen or rub it. You can damage the screen and cause it to change color the next time the monitor is turned on.
- If the screen is very dirty, rinse or change the cloth each time you wipe it. Clean gently and replace regularly.
Step 4. Avoid using ammonia or acetone based products
These materials can easily damage the screen, especially if the monitor has an anti-glare matte finish.
- Use as much plain water as possible to wipe the screen.
- You can purchase a special screen cleaner. Read reviews and check the monitor's manual to ensure that the liquid is safe for the monitor.
- For a mild homemade cleanser, mix equal amounts of water and white vinegar. Use this to moisten (not wet) the cleaning cloth.
- Alternatively, an equal amount of a mixture of vodka or isopropyl alcohol can also be used as a cleanser.
- Always wipe the liquid onto the cloth first and not directly onto the screen to prevent it from dripping.
- Do not use soap that can leave a residue.
Step 5. You can use screen wipes
These wipes are comfortable and specially designed for monitors.
- Make sure these wipes are soft enough for an anti-glare screen, if you use one.
- Read reviews on the internet, or ask the seller to give you a good brand.
Step 6. For stubborn smudges, gently wipe over the smudge on the screen
Use gentle, circular motions to scrub away stains, such as sticky food residue, ink or other substances.
- Don't rub the screen too hard.
- Be patient; the solution may take some time to soak into the stain in order to remove it.
- To help the solution absorb, hold a damp cloth against the stain for a while.
- Do not spray the solution directly on the screen onto stubborn stains.
- Once the stain is gone, wipe the area dry with a clean part of the cloth.
Step 7. Make sure everything is dry before turning on the monitor
This is to prevent moisture from entering the monitor and causing damage, or a short circuit.
Part 2 of 2: Repairing Scratches
Step 1. Check your monitor's warranty
A scratched monitor may be replaceable.
- Check the monitor warranty to see what options are available to you.
- Once you repair the scratch yourself, the warranty will not cover it in case of more serious damage.
Step 2. Purchase a scratch removal kit
Computer and computer parts stores in supermarkets sell these kits for LCD monitors.
- Check the product reviews on the internet to find out the best way for a particular scratch.
- Follow the instructions for using the product first.
Step 3. Try petroleum jelly for temporary scratch repair
Use a cotton swab to apply a thin layer of jelly over the scratch.
- If the scratch is minor, a small amount of petroleum jelly is safe to use.
- Petroleum jelly doesn't repair scratches, but it will disguise them.
Step 4. Use a small amount of toothpaste to polish the scratches
Make sure the toothpaste you are using is not a gel type, or it will not work.
- Apply toothpaste over the scratch using a microfiber cloth or other soft cloth.
- Let dry, then wipe the screen with a clean, slightly damp cloth.
Step 5. Use baking soda to polish the scratches
A mixture of baking soda and water can also be used to remove minor scratches.
- Mix 2 parts baking soda with 1 part water. Add more baking soda to make a thick mixture.
- Apply this mixture over the scratches using a microfiber cloth or other soft cloth.
- Let dry, then wipe the screen with a clean, slightly damp cloth.
Step 6. Use a rubbing compound for severe scratches
Rubbing compound can be purchased from the internet or automotive stores.
- Be careful when using it. Use only for damaged parts, and do a test first in a corner of the screen before using it.
- Rub a very small amount on the screen with a cotton swab, and rub back and forth until the scratches are subtle.
- Leave it for a few minutes, then clean it carefully.
- Clean the screen thoroughly with a cleaning cloth and screen cleaning liquid or vinegar solution.
Step 7. Use clear varnish
Use for very old monitors, or if scratches will enlarge if left untreated. The varnish will cause a slight blur where it is applied to the screen.
- Make a hole in the sheet of paper. The hole should be slightly larger than the scratch. Use this to cover the screen. Make sure everything is covered (keyboard, buttons, etc.) except for scratches.
- Spray a thin layer of varnish onto the paper over the hole, to print the varnish onto the scratch. Remove the paper carefully after to avoid smudging.
- Or, use clear nail polish to prevent scratches from getting bigger. Use a small brush or toothpick to carefully apply the varnish.
- Clear varnish can be found at craft stores and places that sell spray paint.
- Make sure the varnish is dry before you turn on the monitor.
- Always use varnish in ventilated areas.
- Make sure the screen is completely clean before applying the varnish.
Step 8. Understand that this method can damage the screen
Please bear at your own risk.
- For anti-glare screens, this method can create "glossy dots" on the screen.
- Consider the risk a better solution than an unsightly scratch.
- Use your best judgment and apply this method with care.
Step 9. You can purchase a screen protector to prevent future scratches
It's cheap but can keep your screen scratch free!
