Heavy Duty Water Spot Remover instantly erases alkaline water mineral stains from paintwork, glass, and polished metal surfaces. First wash away any abrasive dirt and debris particles from the surface with a car wash, quick detail spray, or waterless wash solution. Buff away any water spot gel residue, then neutralize the gel by rinsing clear with water or re-cleaning the area with a more detailed spray or waterless wash solution. Follow up with a coat of wax or sealant to help protect the surface from future water spot contamination and etching.
