The TotalBoat Aluminum Boat Etch Wash is designed specifically for cleaning and preparing bare aluminum surfaces on boats. Its main strength is its etching action that not only cleans but also brightens aluminum, helping new paint or finishes stick better. It works quickly, removing oxidation, corrosion, and other contaminants within minutes, which is convenient if you want fast results. The formula is ready to use, so there’s no need for mixing, and it’s safe to use on aluminum and galvanized steel, though it should not be used on fiberglass or wood surfaces.

This product is a reliable choice for boat owners looking to clean and prep aluminum surfaces efficiently, with good cleaning strength and safer chemical properties.
