What to use on your screen

The safest way to clean a computer screen is with a microfiber cloth slightly dampened with distilled water. That is the complete answer for most screens—no special products needed. The microfiber cloth traps dust and oils without scratching, and distilled water leaves no mineral residue the way tap water does.

If water alone does not remove stubborn marks, you can add a small amount of isopropyl alcohol (70 percent concentration) to the water, or use a 1:1 mix of distilled water and white vinegar. Dampen the cloth, not the screen itself—moisture should never drip onto the display or seep into the edges. Wring out excess liquid before you touch the screen.

Do not use paper towels, tissues, or your shirt. These scratch the coating on modern screens. Do not spray cleaner directly onto the display. Do not use window cleaners, acetone, or alcohol above 70 percent concentration—these damage the screen's protective layer and can cause discoloration or cloudiness.

Key Takeaways

  • A microfiber cloth dampened with distilled water is the only cleaning method most screens need.
  • Wring out the cloth so it is damp, not wet, and never spray liquid directly onto the screen.
  • Isopropyl alcohol at 70 percent concentration or a water-vinegar mix works for stubborn marks, but distilled water alone is safer.
  • Paper towels, tissues, window cleaners, and high-concentration alcohol all damage screen coatings and should be avoided.
  • Unplug the monitor or laptop before cleaning to reduce the risk of electrical shock and to see dirt more clearly on a dark screen.

Why you need the right cloth

Computer screens have a thin protective coating that reduces glare and protects the display underneath. Paper towels and facial tissues are rough enough to scratch this coating, even if you use light pressure. Once scratched, the coating cannot be repaired—the damage is permanent.

Microfiber cloths work because the fibers are much finer than paper and grip dust and oils without abrading the surface. They are inexpensive and last for years if you wash them occasionally in warm water without fabric softener. You can buy a pack of microfiber cloths at any hardware store, supermarket, or online retailer for a few dollars.

How to clean without damaging the screen

Power off and unplug the monitor or laptop first. This serves two purposes: it is safer, and a dark screen makes dust and fingerprints much easier to see. Wait a minute for the screen to cool.

Dampen the microfiber cloth with distilled water. The cloth should feel damp to the touch but should not drip when you squeeze it. Gently wipe the screen in circular motions, using light pressure. Do not press hard or scrub—let the cloth do the work.

For stubborn fingerprints or dried marks, dampen the cloth with a 1:1 mix of distilled water and white vinegar, or use 70 percent isopropyl alcohol instead of water. Wipe the same way: gently, in circles, with light pressure. If the mark does not come off after two or three passes, stop and let it dry. Rubbing harder will not help and risks scratching the coating.

Once you are done, leave the screen unplugged for a minute or two to may support any moisture has evaporated before you power it back on.

Different screen types and their needs

Laptop screens, desktop monitors, and tablet screens all have similar coatings, so the same method works for all of them. However, some gaming monitors or high-end displays have special anti-glare or anti-reflective coatings. Check your monitor's manual or the manufacturer's website if you own an expensive or specialty display—a few brands recommend specific cleaning products or warn against certain chemicals.

Touchscreen devices like tablets and some laptops accumulate more fingerprints because they are handled directly. The cleaning method is identical, but you may need to clean them more often. Never use a screen protector film on a computer monitor or laptop screen—these are designed for phones and will blur the display.

What not to do

Do not use Windex, Lysol, or other household cleaners. These contain ammonia or other chemicals that dissolve the screen's protective coating. Do not use rubbing alcohol above 70 percent concentration—higher concentrations are too harsh. Do not use acetone or nail polish remover under any circumstances.

Do not spray cleaner directly onto the screen. Liquid can seep into the edges of the display, damage internal components, or cause electrical shorts. Do not wipe the screen while it is powered on—this is a shock hazard and makes it harder to see what you are doing. Do not use compressed air to blow dust off, because the pressure can force particles into the screen's edges or damage the coating.

Preventing buildup so you clean less often

Dust accumulates faster on screens in rooms with poor air circulation or high humidity. A straightforward way to reduce cleaning frequency is to keep the screen away from direct sunlight, heating vents, and air conditioning outlets. These create temperature swings that draw dust toward the display.

Wash your hands before using your computer, especially if you eat or work with your hands. This reduces the oils and debris that end up on the screen. If you use a laptop, close the lid when you are not using it—this keeps dust off the screen and keyboard. For a desktop monitor, a straightforward cloth cover or a cardboard box placed over the screen when the computer is off will reduce dust accumulation.

Frequently Asked Questions

Can I use baby wipes or makeup remover wipes on my screen?

No. Baby wipes and makeup remover wipes contain oils, lotions, and chemicals that leave residue on the screen and can damage the protective coating. Stick to a microfiber cloth and distilled water.

What if my screen has a matte finish instead of glossy?

The cleaning method is the same. Matte screens have a rougher coating that reduces glare, but they are just as sensitive to scratching and chemical damage. Use the same microfiber cloth and distilled water approach.

Is it safe to clean the screen while the computer is on?

It is not recommended. Cleaning a powered-on screen is a shock hazard, and you cannot see dirt as clearly on a lit display. Always power off and unplug first, then wait a minute before you start cleaning.

How often should I clean my computer screen?

This depends on your environment and how much you touch the screen. A laptop in a dusty room might need cleaning weekly, while a desktop monitor in a clean office might only need it monthly. Clean whenever you notice visible dust or fingerprints.

Can I use the same microfiber cloth for my screen and my glasses?

Yes, but wash the cloth between uses. Dust or debris from your glasses can scratch your screen if the cloth is not clean. Wash microfiber cloths in warm water without fabric softener and air-dry them.
