How to Prevent Water Spots Using Wax
What You'll Need Before You Start:
- Car Washing Soap
- Soft Sponge
- Chamois Cloths or Microfiber Towels
- Car Wax
- Soft Cloths
The best way to prevent water spots is by applying a coat of wax to your car. The polymers in car wax compounds create a barrier between your car's finish and the elements, including hard water or acid rain. Applying a coat of wax periodically according to the wax's package instructions can preserve your car's finish and make it look better longer.
To apply wax to your car:
- Follow the above instructions for washing your car.
- Park the car in a shaded area. Bright sunlight will cause wax to haze more quickly, and may make it more difficult to remove.
- Dry the car thoroughly using chamois cloths or microfiber towels. Leaving any water on the car will prevent the wax from adhering well to the paint finish.
- Apply and remove the wax according to the label instructions. Use an applicator, if included, to apply the wax or a soft cloth. Remove the wax with soft cloths, discarding the cloths often to ensure that you are not wiping wax back on to the car's surface.
If, despite your best efforts, your car still has water spots, the culprit may be your water. Hard water is often responsible for water spots that are difficult to remove or prevent. If you do have hard water, it may be wise to install a water softener on your home's water supply. Water softeners can reduce the concentration of minerals such as calcium and iron in your water that can harden and cause spots when water from your water supply dries on your car. Unsure if hard water is to blame? A home water testing kit, available at most home improvement warehouses can clue you in, but a cheaper gauge of your water's mineral concentration is the fixtures in your bathroom and kitchen. If you're often scrubbing hard water stains from your sinks, faucets and other fixtures that come in contact with water, then you likely have hard water.
