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.
