Chemical Guys Heavy Duty Water Spot Remover vanishes away those water spots caused by minerals found in water that dry on surfaces. The acid-based formula gives you the power to wipe away mineral deposits on your vehicle, boats, caravans and all vehicles exposed to water. Water spots can often feel rough and scaly, while the minerals can penetrate and etch surfaces. Thanks to a breakthrough from Chemical Guys, you can wave goodbye to your conventional polishing routine for removing stubborn water marks. The formula breaks the bond between mineral deposits and the vehicle surface, restoring the optical clarity of the surface, leaving them clean and clear. For best results, pour a few drops of Water Spot Remover directly onto the water spots. Gently agitate the surface with a soft and clean microfiber towel/applicator pad. Repeat this process, but this time, adding a little more pressure and formula to remove those particularly stubborn water spots. This process will dissolve the spots and remove them easily, with just a little elbow grease.
