Cleaning Muntz Metal / Naval Brass
Muntz Metal and Naval Brass can be restored and cleaned using a solution of 50% lacquer thinners and 50% water. Clean only with the direction of the grain, rather than against, when cleaning either of these metals. Use a lint-free cloth to clean the surface, then rinse the metal, and finally wipe dry with another clean, lint-free cloth.
