I brake for anodyzing

Does anyone know if anodyzing and brake cleaner are compatible?

Anodizing shouldn't be harmed by any solvents.

However, many alloy firearms parts (such as S&W revolver frames on the silvery-looking stainless Airweights and AirLites, and Ruger 10/22 receivers) are also finished with a paint-like bake-on finish or a clear coat that can be harmed by aggressive solvents such as brake cleaner.

Anodizing is electrically deposited, and is not generally affected by the types of solvents most people use. Brake cleaner will not hurt it.

BUT there are a lot of catalyzed resin coatings out there that look like anodizing, so if in doubt, use some solvent on a patch in an inconspicuous area of the piece.
Never try to educate someone who resists knowledge at all costs.
But what do I know?

Anodizing is a surface hardening process for aluminum. During this process the surface is porous and can be dyed any color. There is a finishing process that seals the pores of the aluminum. If this process is not perfect, the dye can begin to seep out of the surface. Test in an inconspicuous area to be sure.
