Anything to clean windows, real tin in car windows is baked into the glass.
Only use something made to work on monitors/tv's or the distilled water, the cheapest way + maybe the best over long term. The anti glare coating is very thin on tv's, so thin if you took your finger nail to it "hard" it will leave a mark. My Plasma has a little scratch from my cat attacking a bird on the screen, you can only see from less then a foot away & I have a few small marks on my Sony SXRD RP (plastic screen) TV too, nature shows in HD & a cat do not mix
Yes you can get mirco fiber off eBay, Amazon or a local eye glass place. Eye glass "grade" micro fiber is some of the best. I have anti glare/anti scratch coating on my glasses & do not the smallest of scratches after 3 years, I am very picky about my glasses being clean. It 10x's softer then the micro fiber cloth that came with my tv but it cost about 10x's+ more then a generic micro fiber cloth I got off amazon or was it eBay (?) & 100x's softer then that cloth. I also use eye glass "grade" micro fiber cloth on my DSLR, lens, CCD, filters & telescope it is that soft, so (for me) they have lots of uses besides cleaning just my TV's.
& too clean the cloth after, there are 2 ways, with distilled water (no soap) then let air dry or let it dry 100% then take it outside & give it a good shack.
