In the Wega manual it even comments against Windex type cleaners I believe. That thread will give you all the info you need. Just sort out the tube cleaning from the projection cleaning.
That thread in question would be located here.
And, as noted, do NOT use Windex or any other amonia-based glass cleaner. Also, WEGAs take effort to keep clean; the cabinets have venting slats on all sides, so I keep mine covered when not in use.
I've always been told at work not to wipe down studio monitors/video equipment while the monitor is on. This a myth or their some resoning behind it? I've adopted that for the past five years out of habbit now but don't relly know for sure why...
Probably, Will. Your picture quality will not be affected, but you're going to have problems with glare and room reflections.
Peter: When a monitor or display is turned on, the electromagnetic field and static electricity will hamper the proper cleaning of the screen. Always clean a direct-view screen when the set is in standby mode (i.e., "off").
