Water spots are the mineral stains left over after a drop of water evaporates. The specialty gel neutralizes alkaline stains with a mild acid, removing the stuck-on water stain quickly and effortlessly. Water spot damage begins as droplets of water land on paintwork and other automotive surfaces. As the water evaporates, all the minerals inside the droplet are left behind as a stain on the surface. If caught soon enough, these minerals can be simply wiped away during a car wash or with a quick detail spray. If left overnight, the spot may stick harder, but they can typically be removed with a clay bar. Beyond this level of contamination, water spots can etch deeper into the surface and cause permanent damage that may require polishing, wet sanding, and even repainting. 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 more detail 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.
