How to Reduce Tarnish on Brass

Brass that has taken on a brown or black coloring, also called a patina, has become tarnished. This occurs when unlacquered brass, which is a composition of zinc and copper, is exposed to air for several years. Tarnish will add character and depth to antique brass pieces. It will also make others, including brass hardware and decorative items, look dingy and dirty. Preventing and removing brass is the most effective way to reduce its appearance.

Clear brass lacquer
Soft cloth
Tepid, soapy water
1/4 cup white vinegar
Lemon essential oil
3 to 4 tbsp. cream of tartar
Olive oil

Instructions

- 1
  Coat the brass with at least three coats of clear lacquer. The lacquer will prevent or slow the tarnishing process on brass that is kept both indoors and outdoors. Reapply the lacquer once-a-year, or more often if the piece is exposed to the elements outside.
- 2
  Dust brass pieces once-a-week with a soft cloth. This will remove dust that will break down any lacquer or coating on the brass, which will speed-up tarnishing.
- 3
  Wash brass pieces with tepid, soapy water at least once-a-month. This is all that is required for pieces that are not tarnished and have a lacquer finish that is being monitored.
- 4
  Remove any existing tarnish by creating a paste from 1/4 cup white vinegar, five to six drops lemon essential oil and 3 to 4 tbsp. cream of tartar. Stir the ingredients and coat the piece with the mixture. Allow the paste to sit for 10 to 15 minutes before rinsing it away with tepid water. Dry the piece with a soft cloth.
- 5
  Rub the brass piece with olive oil and a soft cloth. The olive oil will not only shine the piece, it will also protect the piece from future tarnishing.
