LCD or computer screen dirty?

The best way to clean it up is with a microfiber cloth VERY lightly moist with warm water. No soap. No solvents. No alcohol of any type. NO WINDEX. NO 409 or any household cleaner. Be sure that if you're cleaning an LCD screen that you apply VERY little pressure, otherwise you can damage the screen.

For an old-fashion CRT screen (NOT A FLAT SCREEN LCD), you can use the same as above or you can use a small amount of water + rubbing alcohol. Be sure that the liquid doesn't drip INSIDE the monitor.

How do I clean the LCD/LED screen without smudging or leaving a water mark


Hi Herkandjen,
Most TV companies recommend only a dry cotton cloth for cleaning the LCD screens. My personal experience is that using a mildly moist clean cotton cloth is the best thing for this purpose. For tough oily marks MILD soap solution can also be used in place of water. Please be careful to apply only very mild pressure while cleaning. Never ever spray the screen with any kind of liquid. Because the liquid if seeped through the plastic frame can damage the electronics inside. Happy viewing.

black ink printing on back of paper


Your paper feed rollers have some black ink contamination: wipe the rollers, all around, with slightly moist tissue paper until there are no more ink evidence coming off the rollers. To moisten tissue, warm water with a very small amount of Windex, dish soap or rubbing alcohol does wonder.
Also clean gently around the bottom of the print head assembly to remove any obvious splatters.
Hope i helps.

what cleaning solution can i use to clean my plasma tv


Most people will recommend using just some distilled water or a very diluted solution of some mild detergent and water and a lint-free cloth. Do not use alcohol or ammonia based cleaners.

what is best for cleaning the screen of a rear projection tv?


A mild detergent soap and hot/warm water.

Use it in moderation.


Mix up some dish washing soap and warm/hot water in a bowl. Use a lint free cloth and dunk it into the water and then wring it out. Wipe the screen down and repeat until clean.

Then use plain water to wipe the screen (on a wringed out cloth) to remove any residue until you have purged and dried the screen.

Tips: Make sure you use a lint free and soft cloth. Make sure you wring out the cloth so that you only have minimal water or soap on it.

DO NOT use alcohol or ammonia based cleaner on the screen.

Expect to spend around 10-15 minutes to properly clean the screen.
