W9 Water Spot Remover is a concentrated formula that is 100% coating-safe. Hard water spots and silica scale will disappear from exterior surfaces with ease. The formula also works well on glass, where watermarks can be exceptionally hard to remove. Use W9 Water Spot Remover on ALL paint types, including matte finishes.
Unlike standard single-mechanism water spot removers, W9 has a three-mechanism approach to removal:
- It dissolves and removes salts
- It traps metal ions, which are commonly found in tap water
- It removes silica scale, which is traditionally very tough to remove
