Still interesting what would be used to polish a gold plated beryllium mirror. For instance, looks like they clean it by spraying CO2 snow: https://en.wikipedia.org/wiki/Carbon_dioxide_cleaning

Yeah, I took a gamble.

Just looked at the reference you dropped. Thanks, that is an interesting little rabbit hole.

Be very careful grinding, polishing or otherwise ablating any alloy that contains beryllium. Berylliosis (no matter if acute or cronic) is no joke.
