Cleaning is undertaken when verdigris and general dirt has discoloured brass work.
A lot of brass work has lost some, if not all, it's lacquered protective coating, and so this has to be fully cleaned off before cleaning and polishing can occur.
The examples are of a letter scale, escutcheon and planter - all these were green/grey before being cleaned.
Brass planter - was green grey
Escutcheon - this was black
Walnut and brass scales
