Hence the question, “how do you remove water spots from windows?”

There are various ways to remove hard water spots from windows, including commercial window cleaning products. These are products you buy over the counter and use to remove the mineral buildup causing water spots. To remove the marks, you can also use DIY options like vinegar, toothpaste, and lemon juice.

If you often get disappointed with hard water spots that ruin your car windows’ appearance, this article will help you solve the problem.

Read to the end to find out how to remove water spots from car windows.

How Do You Get Hard Water Spots Off Car Windows?

Hard water contains sulfates, chlorides, and bicarbonates of calcium and magnesium.

These are minerals that leave stains on windows when water evaporates.

The mineral deposits leave stains when hard water has been used to wash the vehicles without wiping them off before it dries.

Therefore, individuals must learn the correct ways to remove the spots if they are left on the vehicle windows.

You can get hard water spots off car windows using a clay bar, a water spot removal product, lemon juice, vinegar, WD-40, steel wool, toothpaste, essential oils, hydrogen peroxide, and dishwasher rinsing solutions. The methods keep your vehicle windows spotless and prevent eventual hard water damage.

The hard water spots removal methods are explained below:

Use a Clay Bar to Remove Hard Water Spots

You can use a clay bar to remove the spots from hard water to wash your car windows.

A clay bar helps remove contaminants on the windows, including the mineral deposits left by the hard water. However, this method is only effective if the hard water stains are less severe.

Gently glide the clay bar across the spots to remove them.

Use Water Spots Removal Products

Use commercially available water spot removal cleaners like Duragloss 755, Chemical Guys HD Water Spot Remover, and Griot’s Garage Glass Polish.

You can also purchase any other cleaner you prefer and use to clean the marks off your vehicle windows.

The products are specially formulated with certain ingredients to eliminate stubborn water stains.

Some could also clean and simultaneously wax and lubricate the surface, preventing hard water stains from occurring in the future.

Use Lemon Juice

Lemon juice is naturally acidic, so it can neutralize the alkaline properties of the minerals forming hard water to remove stains from car windows.

Slice a lemon and rub it on the hard water spots to remove them.

You can also squeeze the juice out of a lemon and apply it to the stains with a spray bottle.

Then, use a paper towel or a soft cloth to wipe the juice away, leaving a hard water stain-free car window.

Apply Vinegar to Remove Hard Water Streaks

Like lemon juice, vinegar can also get hard water spots off car windows.

The acidic composition of vinegar reacts with the alkaline hard water minerals to neutralize and remove them from the surface.

Mix equal parts of water and vinegar and use a spray bottle to apply it to the windows after wetting them.

Let the solution sit on the windows for around five minutes, and use a clean microfiber towel to wipe it off from the windows, eliminating the hard water stains.

WD-40 as a Hard Water Spots Removal Method

You can use WD-40 to remove hard water spots from surfaces like mirrors and car windows.

WD-40 reacts with the calcium and magnesium minerals in hard water, loosening their bonds to eliminate the stains.

The product is easy to use; spray it on the stained car windows, rub it with a towel and let it sit for at least two minutes, then wipe it off with a dish, microfiber towel, or a paper towel.

Your car windows will be spotless and sparkling clean after that.

Remove the Hard Water Stains With Steel Wool

Use #0000 steel wool to remove the stains from the vehicle windows.

Steel wool may seem pretty harsh on car windows, but the #0000 type is super fine and delivers amazing results when removing hard water stains.

However, caution should be taken when using it; use gentle, circular motions when scrubbing to avoid scratches while eliminating the stains.

Also, the steel wool pad should be wet before being used on the vehicle’s windows.

Use Toothpaste on the Stains

Use a non-gel fluoride toothpaste as an effective hard water stains-cleaner on your vehicle’s windows.

The toothpaste is mildly abrasive, helping you rid the windows of the unsightly marks left by hard water.

Squeeze a small amount of the product onto a palette and add a dab of baking soda or vinegar to it.

Apply the solution over the stains using a damp cloth or towel and leave it on for 5 to 10 minutes.

Then, rinse the window and dab off the excess water with a clean microfiber cloth, revealing spotless car windows.

Apply Essential Oils on the Stains

Orange or lemon essential oils can also help you get hard water spots off your car windows.

The oils prevent hard water spots from forming on the surface in the future, especially if you apply them once a week.

Mix a few drops of the essential oils with water and use a clean microfiber cloth or towel to apply it to the stains.

Let the mixture sit for about 10 minutes, and then use a high-quality glass cleaner to remove it from the windows.

Use Hydrogen Peroxide

Hydrogen peroxide is a readily available cleaning chemical in most homes, and you can use it to remove hard water stains from your vehicle’s windows.

You can combine it with baking soda to confront hard water discoloration and stains on glass car windows.

Apply the mixture directly onto the stains with a soft cloth and gently rub it in.

Let the solution soak for about 30 minutes and rinse it from the windows using water and a gentle car wash cleaner.

Remove the Stains with a Dishwasher Rinse Solution

You can use standard dishwasher rinsing agents to remove hard water spots on your automobile’s windows.

Such agents are specially formulated with ingredients that work on hard water deposits and limescale from glass, and they are just as effective on car windows.

Use a spray bottle to apply the solution to the entire window and let it soak for a while to eat away at the stains.

Use clean water to rinse it off and dry the window with a clean paper towel to reveal the stain-free car windows.
