GTECHNIQ W9 Water Stain Remover Removes water and silica stains Safe for coatings Can be used on all types of paint and vinyl W9 Water Stain Remover is a concentrated formula that is 100% safe for coatings. Unlike standard single-action water stain removers, W9 uses a three-action approach to removal. It dissolves and removes salts.

It traps metal ions commonly found in tap water. Finally, it removes silica deposits that are traditionally very difficult to remove. Hard water stains and silica deposits will easily disappear from the exterior surface.

The formula works well on glass, where traditionally water stains are extremely difficult to remove. Use W9 on all types of paint, including matte surfaces.
