Begin by placing the drum on a soft towel to avoid scratching the shell and to protect the work surface.
Using a dry microfibre cloth, remove all loose dust and dirt from the surface, paying attention to edges and around lugs.
Prepare a very mild cleaning solution using a small amount of dish soap diluted in water. Lightly dampen a clean cloth and wipe the shell gently, working in straight lines rather than circles. Avoid soaking the cloth
Dry immediately with a second cloth. * For wrapped finishes, a dry buff is usually sufficient.* For lacquered shells, apply a small amount of guitar polish or carnauba wax and buff lightly to restore depth and shine. Take care not to allow moisture to sit around hardware fittings. The aim is to clean and lift dirt without disturbing the finish.
