Use a watery solution or a mild commercial glass cleaning solution. Apply (e.g., spray) the solution on the cloth, not on the picture tube.

The cabinet has been tested for resistance to the following products: Cidex, Betadine, Alcohol (Isopropyl and Ethyl), Ammonia-based cleaners (Windex) and Aquasonic Gel.
