*NOTE: Certain coatings have inherently poor adhesion, especially if manufactured without effective substrate preparation, particularly gold and silver coatings and replicated aluminum gratings. That being said, we and our customers have successfully protected and cleaned lots of gold and silver mirrors and gratings including those on the WM Keck Telescope and the Gemini North Silver. The Laser Gravitational Wave Observatory (LIGO) uses our red polymer formula exclusively to clean their gold optics as documented here. While we routinely clean diffraction gratings, the old adage about gratings still holds - don’t touch them unless you have to! And remember: Always test on an inconspicuous or non-critical area first.
