This aggressive cut polish breaks down oxidation, surface tarnish, hazy looking metals and severe rust stains and leaves a lasting sealant! Apply polish to the non-abrasive microfiber applicator and wipe onto the surface. As the liquid starts turning black, the polish is working to remove all the tarnish, contaminants and build-up from the surface. Buff off residue using a clean cotton terry cloth. Contains petroleum distillates.
