I simply use a good microfibre cloth and no solution, the glass on the front is quite tough but the last thing you want is scratching. Also taught the kids to keep their fingers away from the screen but those gloss black frames do get rather dusty.
Problem is, there a couple of smudge marks on the screen itself at the top and I have tried using a microfibre cloth from my spectacle's case and this hasn't worked. So instead I've bought some Plasma/LCD cleaning solution gel made by Philips from Amazon for baout £8.00.
I think if it's just a question of dust a microfibre cloth is fine, but when you have the odd smudge here and there the cloth alone is quite useless.
I suppose those smudge marks are a result of when you wall mounted it, I think any cleaning solution designed for cleaning plasma and (rubbish) lcd sets will be fine and you would have to seriously misuse any thing like that to damage your screen.
You are a 100% correct DJ-The smudge marks and finegrprints are as a result of the wall mounting process which took me about 2 hours to complete. I hope the Philips solution will be fine.........Like you say, even though the screens are pretty durable, you would have to go some way to scratching them adn I guess the maufacturers must take all this into consideration when they make the display? I must admit when I first saw a smudge mark I did use a small piece if kitchen towel and rubbed over it ever so gently but that only made the smudge a bit bigger. Haven't had time to plug eveything in yet-Hopefully this Saturday though once also my DVE disc arrives............and then...........on go all the lights!
