In this case, use very small amounts of the paste or cream on a small portion of the bell. Remove the paste or cream with a damp rag and note the effect on the metal beneath.

Continue using in larger areas only if you see a rich and even reflection in the metal. Perspiration or fluid from your hands can cause continuing discoloration on a horn.
