When brass is exposed to air and high humidity for a long time, it is easy to form an oxide layer and cause discoloration. You can wipe it regularly with a soft cloth dipped in neutral detergent to remove the oxidation layer; you can also spray varnish or electroplating on the surface to form a protective film to delay oxidation and maintain the surface gloss.
