Many metal polishes use harsh acids and substances that are hazardous to the environment. Bio-based Metal Polish from Iosso is different. A USDA Certified Biobased product, it's safe to use around water and other sensitive ecosystems—not to mention people with chemical sensitivities, children and pets.

Made in the USA, Bio-based Metal Polish meets the stringent requirements of the California Air Resources Board (CARB). While safe to use, the formula is powerful. It quickly removes oxidation, tarnish, surface rust and water spots from stainless steel, chrome, aluminum, brass, bronze and copper. It's perfect for cleaning heat bluing off chromed exhaust pipes. Not just for metal, this versatile product also eliminates black marks on porcelain, as well as road tar and oil from Plexiglas, hard plastic and painted surfaces.

Bio-based Metal Polish is concentrated and contains no silicone or carnauba waxes. Using it is simple. A small amount of the creamy paste is rubbed onto the surface with a soft cloth then buffed off by hand or machine. Along with restoring the metal to a high shine, it leaves a protective coating that lasts for months. A one-pound container of Iosso Bio-based Metal Polish costs $25; five pounds is $90.
