How to Remove Water Spots From a Car

Water spots develop on a car's surface from impurities in the air and the water that you use to wash your vehicle. They often appear after you leave your car out to air dry. You can remove them easily and take steps to keep them from appearing in the future.

  • Find a water spot removal chemical from an auto detailing company. Meguiar's offers two different products for this purpose, the Quik Detailer or Final Inspection. RainX is another product that is available in most auto supply stores and big discount retailers.

  • Apply the chemical as directed on the packaging. This is extremely important as the chemicals used to remove water spots contain a potent acid that could damage your paint if used improperly.

  • Wax the car as you normally would after removing the acid. Use the wax as directed to protect your vehicle from water spots and paint damage.

  • Take your car to a professional detail shop. Most car dealerships have their own detail shop and offer packages to customers. This can include a thorough treatment for your car's exterior, including water spot removal, washing and waxing.
