Do you want to get rid of water spots on your car windows? Those pesky white-edge splotches that appear after it rains or snows are remnants of hard water that has dried. While it may seem like these water spots could be simply wiped away, the minerals in the hard water do not allow that. Fortunately, there are a bunch of ways you can remove the water spots on your car windows! Follow Rocket Carwash’s tips, and your windows will be shining in no time!


  • 1 Spray bottle
  • White vinegar
  • Water (distilled or bottled)
  • 100% Cotton towel or Foam applicator pad
  • Microfiber towel
  • One-step polish


Time is of the essence 

When it comes to removing water spots on car windows, time is absolutely of the essence. It will be a lot easier to remove hard water spots immediately after it happens rather than trying to get rid of them after sitting out for hours or days. Unfortunately, because there are minerals that etch into the surface of your car, they are much harder to clean.

How to Get Rid of Water Spots on Car Windows: Wash your car

Wash your car

The first step to getting rid of water spots on windows is to wash the car thoroughly. Visit your local Rocket Carwash in order to remove road grime and dust from your car. This will also help to eliminate some of the minerals in the dried, hard water. Before beginning the spot removal process, make sure the car is completely dry.


Create your vinegar/water solution

After washing and drying your car, mix 1 part white vinegar with one part distilled or bottled water. It is best to avoid tap water because it contains minerals. Pour your vinegar/water mixture into a spray bottle and spray onto the affected windows. You’ll need to allow the mixture to work for up to 10 minutes. The minerals in hard water are more alkaline in nature, the acid in the vinegar will help to neutralize them.

Rinse and wash the car again

After allowing the solution to sit for 10 minutes, wash and dry the car again in order to fully remove the solution. The minerals from the hard water should be mostly gone by this point, but you may still notice rings.


Polish the windows

Using your one-step polish and a foam applicator pad (or microfiber towel), apply the polish to the remaining water spots on the car windows. Buff off the area with a dry microfiber towel. If some spots still remain, repeat this process as many times as needed. 


If needed, use detailing clay

If those pesky water spots are still giving you trouble, we recommend that you use detailing clay. It is much like an artist’s clay in that the clay can be kneaded and shaped. Detailing clay is perfect for the smaller sections of water spots since it forces the mineral residue to disappear.
