WARNING: DO NOT CLEAN THIS MONITOR'S SCREEN WITH ANY PRODUCTS OTHER THAN DISH SOAP DILUTED IN WATER.

This tube has a fragile Diamondtron / Trinitron anti-glare coating which will be damaged by all common cleaning products including Ammonia-Free products. You should only clean it with water or water mixed with a few drops of dish soap. Use only a soft clean microfiber towel to wipe the screen.

If the screen has missing/discolored parts of the finish, or spots that look like scratches that don't come off, or parts where the mirror finish is missing, the coating has already been permanently damaged and should be removed. You can find instructions for removing and replacing the film here.

Many brands used these coatings including Mitsubishi, Sony, JVC, IBM, and more. Usually if the underlying tube technology is aperture grille-based and the monitor is a higher performance PC monitor, it can be assumed the tube has this fragile coating. The user manual of the monitor will also mention not to use any cleaning products on the screen.
