5 Methods For Removing Water Stains From Car Windows


Water spots are not going to physically damage your vehicle in the same way that other substances like splattered bugs or bird poop might, but they can still impact your visibility and make your car look less clean than it is! If water stains aren’t removed they can also begin to become a more permanent feature on your vehicle.  

Once you have these water stains they will slowly but surely build up on the glass parts of your car from the windows to the side view mirrors and windshield and when you’re driving at night and there is glare from another car’s headlights they can really limit what you can see.Unfortunately windshield wipers will not help you here with either type of water spot. 

Did You Know There Are Different Types Of Water Spots

Types of water spots:

  • Regular Water Stains
  • Etched
  • Bonded Mineral Water Spots

Regular Water Spots

You’ve almost certainly seen these before in places like your sinks, bathtubs and showers. They also form on your car and anywhere that comes in contact with hard water. Hard water is water that has yet to have the minerals within it removed. The minerals specifically are magnesium and calcium that are responsible for leaving the milky white deposits that we identify as hard water stains. As the water evaporates, it leaves behind trace amounts of these minerals, which over time build up. When it comes to your car, they build up on the windows and car body. 

Etched Water Stains

You want to remove these water stains immediately, because they can build up to the point that they become etched into the car’s paint. Etched water stains are hard water spots that are exposed to direct sunlight for extended periods of time. These types of water stains can also be caused by extreme heat exposure as well. Removing these types of water stains can be challenging not to mention expensive. If you can remove them at all. 

Bonded Mineral Water Stains

 The final type of water stains are called bonded mineral stains which are from acidic water. Acidic water is full of unhealthy mixins and types of bonded materials. This water will also leave water spots on your vehicle. These water stains are more dangerous than even etched water stains. These water stains will erode your paint and the sealant of your glass windows. It must be taken care of immediately. 

So How Do You Get Water Stains Off Of Your Car 

There are a wild assortment of methods you can use to remove the water stains from your vehicle. When picking one you need to take into account the severity of the water stains and diagnose the type of stain you are dealing with. 

We’ve compiled a list of the best methods for removing water stains from a vehicle and these can be effective for other household surfaces where water stains have accumulated as well. Here they are:

Vinegar And Distilled Water Method

This method is most effective for freshwater spots as the solution is acidic where as the spots are basic. You will need:

  • White distilled vinegar
  • Distilled water
  • A soft scrub brush or sponge
  • A spray bottle
  • A squeegee
  • Paper towels
  • A towel

Step 1:

Mix equal parts white distilled vinegar and distilled water to make the vinegar solution you’ll use to remove the spots. Once thoroughly mixed use a funnel to place this mixture into your spray bottle

Step 2: 

Spray the vinegar mixture on the water spots of the vehicle being sure to saturate the spots. Leave the mixture to set for about 3 minutes. Repeat this step as needed until all water stains are dissolved. 

Step 3:

Soak the towel you are using in the vinegar, you may want to use a bucket to do this, or simply lay the towel across the windshield and spray down with the vinegar solution. You should aim to have the soaked towel across the windshield for 2-3 minutes. 

Step 4:

Next you’re going to put in some elbow grease and gently scrub away the water stains. Be careful not to put a ton of pressure onto the towel, aggressively removing the stains can scratch your paint or the glass windshield as the chemical build up can be sharp on a micro level. The towel should be enough to scrub away the water stains, but if you would like to use another tool a soft sided sponge should also get the job done. 

Repeat these steps and soak for longer periods of time when necessary for especially stubborn stains. If you are soaking for longer, don’t let the solution dry out. Continuously spray the towel with more of the solution every few minutes. 

Step 5:

Depending on what tools you have available, you’re going to dry the window. A squeegee and a dry towel work best, but paper towels will also work in a pinch. Wipe the windshield thoroughly. 

Note: Always test every method in  a small inconspicuous area as some windows are not meant to be treated with some chemicals, even holistic things like lemon juice.
