Renegade's Marine & RV Water Spot Remover safely eliminates hard water spots and mineral deposits while leaving a lasting high-gloss shine. The water-based formula contains polymer sealants that allow for an easy wipe-on application without harsh chemicals. It's perfect for boats, personal watercraft, RVs, automobiles, and more. It can be safely used on fiberglass, plastic, chrome, glass, and painted surfaces.

Some metals, such as aluminum, are sensitive to this product. Spraying onto a microfiber towel until saturated and then rubbing into the surface is advised around areas of metal. Spot checks are always recommended in a non-visible area.
