How do I clean my windscreen?

The best way to clean an acrylic screen is by cleaning with mild soap or a cleaner specifically made for acrylics like the Plaskolite sold on this site under accessories. Never use a solvent based cleaner like Windex on plastic as this may break down the plastic. An ammonia-free cleaner works best for tempered-glass to get a streak-free shine. Lint-free microfiber cloths are a great option to clean either type of screen.
