Shihuiming
An environmentally friendly cleaning agent developed for sensitive materials such as pure copper, brass, red copper, and beryllium copper. It removes processing oil, fingerprints, dust, and mild oxidation layers from workpieces without damaging the substrate or altering dimensions. Ideal for electronic connectors, copper tubing, and copper decorative parts requiring high surface cleanliness and precision.

Specifically designed to remove heavy oxide scale, black stains, and surface dark films formed on copper after heat treatment, welding, or long-term storage. Through chemical polishing action, it rapidly levels and brightens the copper surface, presenting a uniformly bright metallic texture without over-etching or pitting. Provides the ideal surface state for subsequent anti-tarnish treatment, coating, or direct finished appearance — particularly suitable for copper nameplates, copper hardware, sanitary ware, and crafts.
