Kai Hui of MG Chemicals, makers of one of many available LCD cleaners, explains, “The main ingredient in most wipes on the market is water. There needs to be a small percentage of isopropyl alcohol (IPA) to help get rid of the grease from busy fingers.” Some LCD cleaning solutions may include up to 50 percent IPA, according to Hui, but any more than that could damage the screens.

How to Cleaning an Lcd Tv Screen

• I’ve had a few LCDs over the years. Water, IPA & Water, or special commercial cleaners worked on most smudges, & dust (thankfully I’ve never had to deal with crayon, or markers), but everyting I tried left streaks. Remembering how my grandma used to clean windows took care of this problem. If I have really STUBBORN oil-based smudges (fingerprints & such), I use IPA & water (just on the affected area) to get off the oils. For dust & to remove the streaks left from other cleaners (as well as most fingerprints & grime), I use cornstarch dissolved in enough mildly hot distilled water to make it look like milk… Dampen a soft cotton or micro-fiber cloth in the solution, wipe down the screen GENTLY rubbing away any grime, wait for it to dry, then GENTLY buff off the residue with a dry, clean micro-fiber cloth, & be amazed at the results. Not only does this leave the display streak free, but also seems to help repel future smudges. The same solution can be used to clean windows better then any commercial product I’ve tried, but you can also add a bit of IPA, &/or ammonia if needed (on glass, NOT plastics), & wipe off the residue with old newspapers.
• I initially used windex and paper towels on my 52″ Sharp Aquos with not so good results. It was streakey and after some research, I read that this would ruin my screen. Thankfully it did not ruin it, but did not clean it either. A mixture of IPA water and vinegar and a cotton cloth worked wonders.
• While watching movie I popped too much bubble gum and the next day I noticed lots and lots of gum splashes on my lcd screen. I tried water and rag it just spreads it. How can I remove these little dots.
• My daughter (2 yrs old) colored all over my 42in LCD with a pink cheap crayon and I used a pencil eraser to get the crayon off and then used the new clorix greenworks glass and surface cleaner (its all natural no ammonia)to remove the smudges it worked like magic literally because nothing else was working.
• NEVER use abrasives on screen. etc. brillo pads.ajax,it will just scratch your screen and u can toss it out. JUST use a damp soft CLOTH. got info direct from sony.

Since I’d never suggest you spend more money than you have to, I’d start with a clean, soft cloth and regular ol’ tap water. You can add just a capful of isopropyl alcohol to a glass of water if you need something to help loosen the greasy gunk on the screen, so it can wipe off more easily. Get the cloth damp and then apply to the screen instead of splashing the screen and trying to wipe up the liquid; and always — always — use a clean cloth, as tiny, hard particles trapped in the fibers can scratch the surface of your screen.
