I herd windex can Weaken the protecitive covering on an lcd, Is that true?
Personally I get a new finish rag from my car, I dont know what they are called but they are used to polish stuff or take lint from a papertowel off the windows... But ne ways I take one of those and give it a light rub to get all the dust off, but for like stains I dont know because my monitor is like 2 weeks old.
