Copper cabinet hardware fixtures add style to cabinets in the kitchen and bathroom. As the copper handles and knobs are exposed to body oils, dirt and grime, they can become stained and tarnished-looking. Proper care and maintenance of copper cabinet hardware fixtures contributes toward the upkeep of the overall appearance of your kitchen or bathroom cabinets and ensures the copper fixtures are in good shape.
Unscrew the screws on the back of the copper cabinet hardware using the appropriate type of screwdriver.
Mix a 50/50 solution of white vinegar and water and place it in a plastic bowl. Add the copper cabinet hardware to the diluted vinegar solution and make sure there's enough solution to cover the hardware fixtures. Allow the copper hardware fixtures to soak for 10 minutes to loosen dirt and grease buildup.
Scrub each copper cabinet hardware piece with a soft-bristled scrub brush to remove dirt and grime from the surface of the hardware. Scrub the screws, as well, so they do not transfer dirt or grease back onto the copper hardware when you put it back on the cabinets.
Pour a quarter-sized amount of copper-cleaning paste onto a clean cloth. Rub the paste into the copper surface to remove tarnish, as well as any last traces of dirt.
Buff the copper cabinet hardware with a different cloth to remove the paste and add shine.
