How to Refinish Brass Fixtures
- 1). Fully disassemble the fixture to be refinished.
- 2). Remove the lacquer on the brass with a cloth soaked in denatured alcohol. Rub the fixture with the cloth until the coating is gone.
- 3). Bang out any dents in the fixture with a rubber mallet.
- 4). Buff the fixture with a power buffer and buffing compound. The brass should be smooth and shiny when you are finished.
- 5). Apply antique or polished plating and let rest for as long as the package indicates.
