    Product information

    Description

    The KOYO New Sunlite Polishing Compound – Stainless Steel is a water-based polishing compound for maintaining and restoring stainless steel surfaces. It is used by professional sharpeners and knife craftspeople for blade maintenance — removing hairline scratches, surface staining, and unwanted patina to restore a clean, polished finish — and works equally well on stainless cookware, sinks, and kitchen appliances.

    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. Unlike petroleum-based compounds, the Sunlite formula is water-based and carries no solvent odor, making it more comfortable to use in a kitchen or home environment.

    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.
