I have a big LCD screen t.v.its not just fingerprints that im worried about.so i had to lift it onto my stand which is decently high, (i was moving into a new place so i was sweaty) and i had to use my head as leverage to help get it up all the way, so there is a sweat smear on my tv, probably 6 inches by 4 inches.and it will not go away no matter what i use.ive tried a wool sock, t.v cleaning, a wet towel.is there anything to remove sweat from a tv?
Try that soap called, LAVA and smear it on a soft cloth (polyester) and lightly put water on it. Then try to clean your screen.
