How to clean brass

Tarnished brass is ugly! Luckily, most tarnish can be removed in a few easy steps.

1. Brass often has a clear lacquer on it to protect it from corrosion. This protective coating wears away in time, leaving the underlying metal exposed to the elements. If there is old lacquer remaining on your brass parts, it must be removed. There are many commercially-available products for paint and lacquer removal.

2. Once the old lacquer is removed, the parts must be washed in soapy water to remove chemical residue and any dirt.

3. Any remaining tarnish can be removed with a mixture of white vinegar, table salt, and hot water. Add 2 tablespoons of vinegar and 2 tablespoons of salt to 2 cups of hot water. Use a hand towel to scrub the parts with the mixture.

4. After the tarnish is removed, wash the parts again in warm soapy water to remove any residue.
5. Dry the parts thoroughly.

6. To provide lasting protection, the parts should be re-lacquered. There are many commercially-available spray on lacquers that are both easy to use and highly effective. 

7. For parts that are heavily or extensively tarnished, the services of a professional metal polishing and restoration company may be needed.
