Ways To Effectively Remove Water Spots from Car Windows

You’ve just cleaned the inside and outside of your windshield, but you’re still seeing small white spots. Alternatively, you may have come out of the car wash dissatisfied that those small white spots are still there. You may wonder what are the options to eradicate water spots.

Certain types of water include a high accumulation of minerals, such as calcium and magnesium. When this abrasive water dries, it leaves behind a mineral residue. Due to this, you’re left with a cloud of white spots that is unremovable with standard car wash techniques. Additionally, they impart a gritty feel to your glass and are difficult to remove.

So, here we will discuss the options and various ways to remove water spots from car windows.

Reasons of Hard Water Spots On Car Windows

Consider why hard water spots formed in the first place before learning how to eliminate them. Hard water spots on car windows emerge when mineral-rich water is allowed to dry on the glass rather than cleaned away. Minerals are left behind after all the water evaporates which causes hard water spots on car windows.

While rainwater can cause spots on windows, other factors are more likely to be at fault. Is there a nearby sprinkler splashing water on the windows? Is rain pouring from the roof onto the glass of car window through the gutters? Addressing these issues can help you to eliminate water spots entirely!


Types of Water Stains

Regular Spots

This is the most frequent sort of water spots, which occurs when hard water deposits minerals, particularly calcium and magnesium, on the surface of your car. The source of the water could be anything that comes into contact with your car—from sprinklers, showers, and car washes to rainwater. Eventually, chalk-like deposits or limescale begin to form, and before you know it, your car’s windshield and body are covered in those regular water spots.

Water Stains That Have Been Etched

When water spots are exposed to bright sunshine or extreme heat for an extended period of time, they can etch into the paint of the vehicle. That is why it is essential that water stains be removed before they become a larger issue. To be sure, severe etching can be extremely difficult and costly to erase, as it may require the use of abrasive procedures like wet sanding or the assistance of a certified specialist.

Bonded Mineral 

Consider the following scenario: There is a forest fire someplace, and the smoke from the fire rises into the nimbostratus clouds, where it mixes with water droplets. Whatever it is, it could be regular smoke from vehicle exhaust pipes or industrial emissions that combine with dark clouds. Following that, it rains, and the acidic rainwater finds its way onto the glass and body of your car. The problem is that acidic water is tainted with pollutants and bonded minerals, which cause water spots on your vehicle.

If you don’t address it immediately, don’t be surprised when the water spots corrode the paint on your vehicle and transform your windows into something unsightly.

Now that you’re familiar with the types of water spots that are likely to occur in your vehicle, let’s dive right in and examine the procedures for removing water stains from your vehicle’s glass.

How To Get Rid Of Water Spots?

Always use gloves and protect your hands, especially your eyes, from any contact with the cleaning solutions.

1. Utilization of a Glass Cleaner

Conduct research and select a reputable window or glass cleaner. Scrub the water stain or area with a microfiber cloth. In most circumstances, this procedure works best with typical spots, as it prevents the glass substance from being mistakenly worn down. We suggest using a microfiber cloth as it is non-abrasive and does not leave fibers on the glass.

2. Utilization of Vinegar

Vinegar is naturally quite acidic, and when combined with water, it can be used to remove water spots. If used properly, this mixture can stain without causing damage to the glass beneath. Ensure that you wipe it clean once more with a microfiber cloth.

We propose spraying with vinegar and water solution in a spray bottle. Ascertain that the solution includes an equal proportion of each liquid. Using too much vinegar can cause damage to your car’s window. Allow the mixture to soak on the glass before washing away the mineral accumulation in the mineral-heavy sections of the water spot. If you’re working on the interior, spray the mixture onto your microfiber to avoid contacting internal components. Utilize a dependable interior cleaner to clear up any inadvertent accidents.

3. Utilization of Lemon Juice

Cut a lemon and extract the liquid as a substitute for the vinegar solution. You may simply rub a slice of lemon on water spots, as squeezing enough lemon juice to fill a bottle takes much time.

Ensure that you apply sufficient pressure to obtain enough acidic juice to complete the operation. After that, dampen a microfiber towel and attempt to rub away the water spot gradually. A spray of glass cleaner over the top should assist in removing any remaining streaks or dirt.

4. Utilization of Baking Soda

Make a paste by combining a tiny amount of water and baking soda. Apply it on a microfiber cloth and scrub the water spot vigorously. The baking soda mix can erode the minerals as it contains abrasive grains.

After completely washing the location, thoroughly rinse the glass with water. Due to the possibility of dirt or paste scattering throughout the interior of your automobile, we recommend that you use this method exclusively for outside windows. It is recommended to use newspaper and a normal glass cleaner to remove streaks from your window glass.

5. Utilization of Toothpaste

Additionally, you can use a water-to-toothpaste mix in this situation. Cleaning and properly drying your car’s glass with a normal glass cleaner is the next step.

6. Utilization of Essential Oils

Orange or lemon essential oils might assist in removing hard water spots from the windows of your car. Additionally, they can assist in preventing future hard water deposit formation. After blending a few drops of essential oils with water, put the solution to your car window using a microfiber towel or sponge. Before removing it with a glass cleaner, let it soak.

How Can You Guard Your Car’s Windows Against Water Spots?

While eliminating water spots is the initial step, your work is not complete until you have protected your glass from future spots. To avert water spots on car’s windows, you should:

  • Avoid accumulation and treat water spots immediately.
  • Eliminate any collected water on your glass and windshield.
  • Park your car in a sheltered area to avoid getting your windshield wet.
  • Apply water repellant to the windshield and glass.

You do not have to spend money on pricey spot cleaning chemicals or send your automobile to a professional detailing shop. Just use one of the straightforward treatments suggested above, and don’t forget to couple it with a glass coating and a quality glass cleaner.


Are Water Spots Difficult to Remove from Car Windows?

Water spots are notoriously tough to remove due to the presence of materials in water, even more so when they cover the full surface of your automobile windows. But, nothing to fear. Following the above steps, it will be easy for you to remove water spots.

Can I Use Dish Washing Powder to Remove Water Spots?

Light water spots on car windows can be removed by a simple mixture of water and dishwashing agent.
