How to Lacquer Brass Cabinet Knobs

Remove the cabinet knobs from their places on the cabinets. Unscrew any screws or nuts holding the knobs in place; put the screws in a safe place so that you will not lose them while you work. Take the knobs to a well-ventilated work area and set them on a drop cloth or other protective surface.

Wash the bronze knobs with a soft rag dampened in warm water mixed with mild dish detergent. This initial cleaning will remove surface dirt and dust and expose the old lacquer to your removal efforts. Rinse the surface with clean water and dry with a soft towel before continuing.

Wear protective gloves when working with chemical cleaners. Dampen a cotton swab in acetone and rub the brass surface thoroughly; the acetone will dissolve the old lacquer finish on the knobs. Use a toothbrush to get into crevices or hard to reach areas. Apply acetone until all old lacquer is removed.

Apply a professional brass cleaner to the knobs. These products, available at jewelry or furniture specialty outlets and some home improvement and hardware stores, will dissolve any remaining lacquer and remove oxidization, tarnish, stains and oils that could damage the brass. Rub the cleaner on with a soft cloth; use as little cleaner as possible to remove stains, as too much cleaner can damage the brass surface.

Apply a thin layer of lacquer to your brass knobs. Many lacquers come in spray cans for direct applications; follow all product instructions for specific details. Allow the first coat to dry and apply a second; you will achieve a more even finish and shine with multiple thin layers than with one thick layer. Apply as many layers as necessary, and allow the lacquer to dry completely.

Replace the knobs onto their proper cabinets once they are completely dry.
