Gtechniq W9 Water Spot Remover is a professional three-action formula specifically engineered to eliminate hard water spots, mineral deposits, and silica scale from paint, glass, and exterior surfaces without damaging the finish underneath. The formula works by simultaneously dissolving mineral salts, binding metal ions, and breaking down silica scale, attacking water spot contamination at every level for complete removal even on baked-on deposits that standard cleaners cannot touch.

Safe on all paint types including matte and satin finishes, and safe on ceramic coatings, sealants, and waxes. Works on everything from light fresh water spots to heavily etched mineral deposits from hard water, sprinkler systems, and acid rain. Apply, allow to dwell, agitate gently, and rinse clean. Follow up with your preferred protection product to seal the freshly cleaned surface.

If you are looking for the best water spot remover for car paint and glass, a professional Gtechniq water spot treatment that is safe on ceramic coatings and matte finishes, or a hard water mineral deposit remover for automotive detailing that actually removes the full spectrum of water spotting from light to severe, W9 is the most comprehensive water spot solution in the Gtechniq lineup. Available in 250ml, 500ml, and 1L.
