Hey guys! I'm interested in knowing the best ways to clean horns such as the Edison red Fireside, or any Columbia client machine without losing the paint or dye. The color red appears to be the most unstable. Thanks, Jay

My understanding was that Columbia used a tint mixed in with shellac to make those beautiful translucent-color horns. If it's at all possible to save the original, I usually use a liquid car cleaner-wax for the project, and it seems to do the least damage to the original finish, while making it look pretty nice.

You also have to watch out for some of the old paints (usually shellac or lacquer based). The shellac and lacquer base carrying the pigments are in a constant state of decay/deterioration as a result of the natural 'curing process' (which continues until the shellac/lacquer eventually turns to dust). Add to this the fact that generally the dyes used in shellac and lacquer are not only alcohol soluble, but are usually also water soluble. Aniline dyes are the usual pigments used.
The good part is that you can re-tint deteriorated finishes with water soluble aniline dyes or re-create the original finish using the same techniques if needs be.
