Product information

Description

The KOYO New Sunlite Polishing Compound – Aluminum is a water-based polishing compound formulated specifically for aluminum surfaces. It removes oxidation, light staining, and surface dullness from aluminum cookware, pots, utensils, and kitchen equipment, restoring a clean, bright finish without abrasive damage to the softer metal.

The compound is applied in small amounts to a soft cloth and worked over the surface with light, straight strokes rather than circular motions. After polishing, the surface is wiped clean with a separate dry cloth. Like all compounds in the Sunlite line, the aluminum formula is water-based and carries no solvent odor.

Each jar contains 100g, suited for regular maintenance use. Do not use on brand new surfaces or surfaces that are already in like-new condition.

Koyosha (光陽社) is a Japanese manufacturer based in Tokyo, founded in 1926. Their water-based polishing compounds have been used by professional sharpeners, knife makers, and craftspeople across Japan for decades and are recognized internationally among serious knife enthusiasts for their effectiveness and petroleum-free formulation.
