I "wet clean" my plasma TV so rarely I'm not worried about it but if I did need to clean often, distilled water with a small amount of Ivory dishwashing soap would probably be my choice. Also note plasma TVs are glass, not plastic, so they won't cloud or scratch easily. Having said that, I have used Windex on my plastic motorcycle helmet visors for many years (clear and tinted) and have yet to see any ill effects, go figure.

That's great, like I said, I'm sure it cleans well. I just am opining that I think water is perfectly adequate for just about any AHer who cares, and it's not like it costs more than Windex. Plasma glass doesn't get nearly the outdoor abuse of exterior glass, let alone a helmet visor for motorcycling.
I just wanted to share my research with others so that they may be informed before they followed your method, or anyone's method for that matter. Like I said in the other thread, the worst advice I've ever received here that I followed through on, IMO, was the use of presoaked glass wipes on my PJ. So you could imagine how I'd feel if I actually used a combination of ammonia + alcohol. I wish someone like me was around to stop me at that time, rather than confirming the poor choice.
edit: BTW, there are also the anti glare filters on the glass as well, and AFAIK they are often put right on top of the plasma glass. You will see in the automotive industry that ammonia is just about never used or recommended for glass, in the case there is a film/tint which can be ruined by ammonia. Just because one person uses it without issue doesn't mean there isn't a need to educate everybody else about the risks. Is the AR filter immune to ammonia? No idea, but I don't want to find out, especially if there wasn't a need for that cleaning power.
