Rusty reeds can be cleaned by rubbing out the rust with fine steel wool or by using a commercial rust remover, such as Naval Jelly. When using these products be sure to follow the directions on the label very carefully. If you use the rust remover, work it between the dents of the reed with a small brush (a toothbrush works well). Rinse the piece very thoroughly. We suggest doing this outside with a hose. Dry it immediately (use a hair dryer, if possible). The tape on the top and bottom edges of the reed may come loose. You can replace it with a cloth tape or duct tape and trim it to size with a knife or razor blade.
