Cleaning the screen


The screen is made of plastic. It should be cleaned only with water and a damp cloth. The mirror inside the set however may be cleaned with glass cleaner, carefully as not to drip any on the boards as it will corrode connections. And the internal lenses themselves are made of various materials and typically clean well with 70% isopropyl alcohol.
