Using a cloth or paper towel that is too wet can result in excess cleaner getting in ports and causing significant damage to your PC.
Moisture Damage: If the cloth was too wet, moisture may have seeped into the screen or the device itself, potentially causing temporary or permanent damage.
The best way to clean a monitor is to use a soft, clean, damp cloth to gently clean the surface of your monitor. You may want to dampen the cloth first with some warm water to help get it wet. Don't use a wet cloth, though, because it can cause the screen to warp.
You should never use any kind of dusting or damp wipe cloth inside a PC. Besides using or generating static, or conducting electricity which can damage some components, they also leave fibers behind that attract dust and moisture later on.
Is it safe to clean a PC case's outer surface with wet wipes? Absolutely. You could even use a wet washcloth and some Windex. If you don't have any window cleaner, any mild (multi surface) cleaning product should be okay.
When wet components are exposed to moisture, they can short circuit. This rush of electricity can cause issues for everything from your motherboard, connectors, hard drives, and more.
Use a microfiber cloth: This is the safest and most effective material for cleaning computer screens. Avoid liquid cleaners if possible: A dry soft cloth, such as a microfiber or lint-free cloth, is often sufficient for removing dust and light smudges.
Lightly dampen a microfiber cloth with a mild soap solution or use laptop cleaning wipes. Gently wipe down the laptop's exterior, including the palm rest and touchpad. Pay extra attention to frequently touched areas. Use a dry part of the cloth to remove any excess moisture.
The excessive moisture will settle on the computer, resulting in corrosion and component failure. But the biggest environmental threat to computers isn't high humidity, it's low humidity.
Do not use a vacuum cleaner or hair dryer to clean your PC fan. This may create static buildup and discharge into the sensitive electronics inside the computer case.
Don't use household disinfecting wipes on your computer screen. The same goes for your old T-shirts that you've saved from the last time you had to help a friend paint their walls. Save that for the next time you have to wipe down the bathtub, not your computer screens.
Start by turning off and unplugging the monitor. Then, use a microfiber cloth dampened with distilled water to wipe the screen gently. Avoid using excess water or any harsh cleaning solutions. For stubborn smudges, you can use a screen-cleaning solution specifically designed for touchscreens.
Paper Towels - While not the most elegant cleaning solution, paper towels get the job done when cleaning the outside of a computer or any cases with glass viewing windows.
Use a microfiber cloth.
Never use a paper towel, old t-shirt, or napkins to clean your computer monitor. At worst, the fibers in these materials may scratch the surface of your screen and at best, they'll leave a trail of lint.
Turn the laptop upside down to drain remaining excess liquid (see Figure 4). If you have one, use a blow dryer on the coolest setting and carefully dry the keyboard and any parts you have removed. Keep the dryer moving over all parts. Let the laptop air dry upside down for at least one hour; 24 hours is preferred.
While water damage can ruin a computer completely, many can recover after an accident like this.
When temperatures dip below 32 degrees Fahrenheit, liquid freezes, which can cause permanent harm to your LCD screen. That's the number one reason to ensure you never leave your computer in a cold car or even on a cold floor overnight.
Place silica gel packs inside the computer case or near its surroundings. Silica gel is an excellent moisture absorbent and can help minimize humidity-related damage to your computer's internal components.
Never apply liquid cleaners or water directly to any part of the computer. Always dampen the cloth, cotton swab, or magic eraser and use that to clean. It should only be damp enough to just know that it is not dry. Water, or liquids, and electricity do NOT mix.
A vacuum can create static electricity that can damage computer components. A vacuum can also create enough suction to make your fans spin hard enough to damage them. Don't use a feather duster or rag, either. Rubbing components can damage them.
How do I clean my laptop keyboard without removing keys? Use compressed air to remove debris, then clean with a slightly damp microfiber cloth. For stubborn dirt, use a cotton swab lightly moistened with isopropyl alcohol.
Work on a hard surface:
Your PC should never be placed on materials such as carpet, blankets, or towels when handling your PC in situations where you need to handle the internal components.
As already mentioned, split-strand shredded fibers are what give microfiber its best superpowers, increasing absorption, reducing dry time, creating friction, and making static electricity to attract and trap dirt.
