Positioning

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.

Features

• Rapid brightening: Quickly restores the native metallic luster of copper parts with uniform and brilliant color.
• Eco-friendly, no heavy metals: Completely eliminates highly polluting components such as chromic acid and nitric acid from traditional formulations, with simple and compliant wastewater treatment.
