W9 Water Spot Remover is a concentrated formula which is 100% coating safe.

Unlike standard single mechanism water spot removers, W9 has a three mechanism approach to removal. It dissolves and removes salts. Traps metal ions, which are commonly found in tap water. And finally, removes silica scale which are traditionally very tough to eliminate.

Hard water spots and silica scale will disappear from the exterior surface with ease. The formula works well on glass, where traditionally watermarks are exceptionally hard to remove.

Use W9 on all paint types, including matte finishes.
