General rules for brass

Use mild soap and a soft cloth, rinse and dry immediately. Do not polish a coated or plated finish, and avoid bleach, strong acid, alkali and abrasive that can strip lacquer or change patina.

Check the label

Identify unlacquered living brass, lacquered brass or a brass-effect plated finish before cleaning. Patina can be intentional.

Stains on brass

Brass can be damaged by a cleaner that is harmless on another surface. Identify the substrate, coating, finish and adjacent parts before treating a stain.

Use the least aggressive route

Use mild soap and a soft cloth, rinse and dry immediately. Do not polish a coated or plated finish, and avoid bleach, strong acid, alkali and abrasive that can strip lacquer or change patina.

Judge only when dry

A remaining patch may be residue, a changed patina, coating loss or absorbed contamination. Stop if a hidden test changes colour, gloss, texture, adhesion or strength.
