How to Remove Water Stains from Car Glass


Water stains! They don’t sound serious as squashed bugs, splattered eggs on the windshield, tar, overspray or other types of nasty-looking dirt. But don’t be fooled, those little white spots can build up in your side mirrors, windshield and rear glass making it difficult for you to see at night.

It can get even worse when it starts raining and the wipers won’t do much to solve the problem. So how To remove water stains from car glass?

Just take a magic wand, say ‘evanesco’ and the water stains disappear? Well, you’re not a wizard and it’s not that easy. There is a due process to be followed and you have to know what you’re doing. First, let’s have a look at the types of water stains that can infiltrate your vehicle.

Types of Water Stains

Regular Water Spots

This is the most common type of water spots, usually formed when hard water leaves mineral residue especially calcium and magnesium on your car surface. The source could be any water that hits your car- from the sprinkler, showers, car washes to rainwater as the culprit. Eventually, the chalk-like deposits or limescale start to form and before you know it, your car glass and body are filled with those regular water spots.

Etched Water Stains

When water spots are exposed to direct sunlight or intense heat for a long period, they can engrave into the car’s paint. That’s why it’s recommended to remove water stains as soon as possible before it becomes a bigger problem. Mind you, severe etching can be very difficult and expensive to remove since you may be required to use abrasive techniques such as wet sanding or consult a qualified professional to help you out.

Bonded Mineral

Picture it like this: There is a forest fire somewhere and the smoke emission rises into the nimbostratus clouds and mixes with water droplets up there. Whatever, it could be regular smoke from vehicle exhaust pipes or emission from industrial plants that mix with the dark clouds.

Afterward, it rains and the acidic rainwater finds its way onto your car glass and body. Here is the thing; that acidic water is full of contaminants and bonded minerals that leave water spots on your vehicle.

If you don’t take care of it pronto, don’t be surprised when the water spots erode your vehicle’s paint and turn your windows into something ugly. You’ve been warned! Now that you know the types of water spots that you will likely encounter in your vehicle, let’s jump right in and explore the techniques you can use to remove water stains from your car glass.

The Vinegar Solution Method

Since water spots deposits are alkali in nature, you will need an acidic solution such as vinegar to do the magic. However, this method is more effective when removing freshwater spots.

What You Will Need

  • White distilled vinegar
  • Distilled water
  • Spray bottle
  • Squeegee, paper towel or dry towel
  • Rough towel

The Process

Step 1. Fill the spray bottle with equal parts of distilled water and distilled vinegar on a 50/50 ratio. Shake the spray bottle for a few seconds after filling it to blend the solution and achieve the desired results.

Step 2. Spray the vinegar and water solution onto your car glass. The objective is to saturate the water spots and leave it for 1 or 2 minutes to allow the vinegar to soak. If you notice any dirty areas on the glass with concentrated water spots buildup, you can reapply the solution.

Step 3. Immerse the rough towel in vinegar and water solution until it is wet and stretch it out over the sprayed parts of your car glass. It is okay to place the wet rough towel over the glass for a minute or two to treat the water spots efficaciously.

Step 4. Scrub the car windows and mirrors gently. Do not scrub aggressively since that may leave scratches on your windshield, side mirrors, windows, and rear glass. The abrasive bumps on the rough towel are enough to remove the water stains off the car glass with a light touch.

Step 5. If the water stains are not coming off easily, let the solution stay on the glass for a longer period. You can re-apply it if dries out. Don’t allow the solution to dry on the surface.

Step 6. Use a squeegee, paper towel or dry towel to clean off the vinegar and water solution on the car glass. However, make sure the car glass is wet with the solution before you bring in the squeegee, dry towel or paper towel to do the finishing touches.

  • Treat your car glass with a water repellant. There are some water repellant products you could use on your car glass to act as a buffer and prevent water stains formation. However, make sure the water repellants are specifically formulated for car windows and they won’t interfere with visibility.
  • Mind where you park. Whenever you’re parking, find a spot where your vehicle won’t be exposed to hard water. For instance, if you want to avoid acidic rain filled with bonded mineral residue, the best place to park your vehicle is in an enclosed garage.
  • Wash Your Car Regularly. Sometimes, water stains overwhelm the car windows after the car has been neglected and abandoned. Fact is, if you wash your car regularly and spray the windows with a vinegar solution at least once per week, you will unlikely have a water stain problem.
  • Don’t air dry. After washing your vehicle, don’t air dry it. If you leave your car to air dry, don’t be surprised to come back and find watermarks on the windows. Instead, use a microfiber cloth, paper towel, squeegee or a soft towel to wipe and dry the windows.
