Whether it's considered a weekend toy or a lifelong investment, boats, aircraft, RVs, motorcycles and collector cars all have metal that will eventually look undesirable. To keep them looking their best, savvy owners use Iosso Metal Polish. It leaves a brilliant protective shine that lasts for months.

Iosso Metal Polish quickly removes oxidation, tarnish, surface rust and water spots. It takes care of blue heat stains from motorcycle exhausts and gets rid of road tar and oil.

Unlike some cleaners, Iosso Metal Polish works on stainless steel, chrome, bronze, brass, aluminum and other precious metals. It even works on porcelain, acrylic, hard plastics and painted surfaces.

Highly concentrated, Iosso Metal Polish is easy to use by rubbing it on with a soft cloth and buffing it off by hand or machine. It doesn't contain silicone or wax, so it doesn't leave a greasy film.

A 3 oz. tube of Iosso Metal Polish costs $9; 1 lb. is $23; and 5 lbs. is $88. A USDA-certified bio-based version is available that complies with California Air Resources Board (CARB) regulations.
