🧴 Copper and Brass Polishing and Cleaning Liquid – Production, Formulation and Properties
Overview:
Copper and Brass Polishing and Cleaning Liquids are specialized acidic cleaning formulations designed to dissolve oxidation, tarnish, and corrosion residues from copper, brass, and bronze surfaces.
They restore brilliant metallic shine while preserving the surface integrity and preventing over-etching.
These liquids are used across metal polishing industries, jewelry workshops, and household cleaning, providing fast, uniform, and safe restoration for decorative and industrial metal items.
Their balanced chemistry ensures effective cleaning with minimal effort, leaving behind a thin anti-tarnish protective layer for extended brightness.
Production and Formulation:
Copper and brass polishing liquids are formulated by blending mild acids, surfactants, chelating agents, corrosion inhibitors, and polishing enhancers in deionized water.
The components are mixed under gentle agitation to ensure chemical stability and uniform clarity.
Optional additives such as fragrance oils, wetting agents, or anti-tarnish polymers can be included to enhance user comfort and performance.
The formulation is adjusted for controlled acidity (pH 2.5–4.0) to ensure powerful tarnish removal without damaging the metal.
The final product is filtered and filled into plastic or glass containers for direct application by dipping, brushing, or wiping.
