🟠 Copper and Brass Polishing and Cleaning Products – Production, Formulation and Properties
Overview:
Copper and Brass Polishing and Cleaning Products are advanced formulations designed to remove oxidation, tarnish, and surface discoloration from copper, brass, and bronze alloys, restoring their original shine and metallic luster.
These products are available in liquid and paste forms, catering to different cleaning needs — from fine jewelry and decorative items to large industrial parts.
Over time, copper and brass surfaces react with air and moisture to form dull oxide layers; these formulations provide controlled chemical and mechanical cleaning, effectively removing those deposits without damaging the metal.
Widely used in metal finishing, restoration workshops, home maintenance, and industrial polishing, they represent a balance between powerful performance and safe metal care.
Production and Formulation:
Copper and brass polishing products are produced by combining mild acids, surfactants, corrosion inhibitors, fine abrasives, and brightening agents in carefully balanced proportions.
Liquid types are formulated as aqueous or solvent-based systems, while paste types incorporate micro-abrasive polishing powders to enhance cleaning intensity.
Optional ingredients such as anti-tarnish compounds, waxes, or protective polymers can be added to prevent re-oxidation and improve surface gloss.
The production process involves gentle homogenization, pH adjustment, and stabilization, ensuring safe yet effective tarnish removal.
Finished products are packed in plastic bottles, tubes, or jars, depending on their viscosity and intended use.
