Water Spot Remover
W9 Water Spot Remover is a concentrated formula that 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 the silica scale which is traditionally very tough to remove. 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.
