One of the nice things about old style CRTs is that you could simple spray polish onto the screen and wipe clean. Try that with an LCD and you can end up ruining it; even worse spill liquid on an LCD and it's ruined as I found out with the wife / juice / laptop combination. The problem is my laptop screen had developed smears and the wife's laptop screen was filthy. I had to do something. Lots of googling later and I discovered KlearScreen. The marketing talk looked ok;
Klear Screen is the only formula used, sold, or recommended by leading manufacturers such as Apple, Dell, Sony Vaio, HP/Compaq, Fujitsu, IBM, Panasonic, Samsung, Sharp, Toshiba, and ViewSonic.
However it still needed you to spray liquid on the screen, which was scary. Still, nothing ventured, nothing gained, and I have an LCD monitor upstairs in the server room to test it out on. I managed to find a UK supplier, ScreenClean.co.uk (they had the starter kit and no-one else seemed to) and they took paypal which was useful as I have some credit in my paypal account. I placed the order yesterday and this morning my "Super Starter Kit with Micro-Chamois" arrived. So I crossed my fingers, sprayed the screen and rubbed. The results are stunning. The laptop screen is like new, the wife's screen took a couple of applications but it's now brighter than it's ever been. KlearScreen is highly recommended, and if you're in the UK then place your order with Philip Jones at screenclean for a speedy turn around. Endorsements all round (not that I'm exactly that important to give useful endorsements, but hey, one of you reading this might believe everything I say.)
