The Blue Label KOYO Sunlight Polishing Compound Paste is a water-based polishing/buffing paste for knife blade maintenance including polishing, removing hairline scratches and dirt, restoring lusters, as well as removing unwanted patinas. Simply apply a small amount of compound on a piece of soft, clean cloth, then gently wipe on the surface of the blade back-and-forth. After that, wipe the surface clean with another clean, dry cloth. Polishing by gently buffing back and force in straight lines, and avoid circular motions.
