The best way to polish our pieces is with a muslin buff and a polishing compound. Red rouge works good on most brass pieces. If the piece is enameled, try a sample to make sure the polish will not hurt the enamel. Avoid polishing the enamel of a piece if at all possible. You can damage the enamel. Although we use a motor mounted buff smaller ones are available for drills and for rotary tools. Another possibility is to use a commercially available brass cleaner such as brasso or any bathroom fixture cleaner. These will clean and polish bronze, but are not as effective as the buff method. There are also many dip jewelry cleaners available. Some of these work well on enameled pieces. Try a small sample first to see if the dip might harm your enamel first.
