I have been reading a lot on avs forum and all over the web , and doing some search for the last few days on how to clean fingerprints oily residue , dust that has been hard to remove and , dark spots and other stains on my Samsung KS8000 TV. There is endless videos and recommendations on how to clean the TV screen , from soapy water with a microfiber cloth to alcohol 90% to chemicals sold online. :/ Long time ago i bought some TV and monitor screen cleaner on Bestbuy , it was a blue bottle and i tried that on an old monitor lcd screen , but it made it worst and i got more stains with that chemical that i could never get it out, so i threw away that screen cleaner and now i'm afraid to use harsh chemicals that claims to clean lcd screens. I need someone who have successfully clean hard stains , fingerprints , etc... on their screens without damaging it or make it worst. What have you guys used that really works ?
