Soda powder is used by archeologists in small air powered air-brush like
tools to clean rock and mineral dposits off of fossil bones. Soda
applied this way can be used to frost glass, or to clean paint or metal.
It is a very fine abrasive and the abrasive action can be used for fine
cleaning and polishing. It is easily dissolved in water for clean up. It
would be ill advised to use it on mating surfaces of parts but it can be
used on other surfaces.
Regards.
