How to Remove Water Stains From Car Glass

Water stains may not be as harmless as you may think. If you leave water on car glass, droplets may form stains and may be hard to remove with ordinary glass cleaners. Hard water spots are due to minerals like calcium and magnesium in water, including chemicals that leave mineral deposits and limescale. Water stains are a mixture of soap, water, acid rain, and sodium, and we have time-tested techniques on how to remove water stains from car glass.

What causes water spots on car windows?

Water spots are due to the following:

  • Rainwater

Rainwater settles on your car windows, and oftentimes, we don't have time to remove them unless you give your car a thorough wash. Water stains are not just on the windshield, but also on car windows and on the back windshield guide.

  • Regular water

Usually, we use tap water to wash our cars. Tap water has minerals that can remain on the glass and cause water spots. It's best to thoroughly rinse your car, especially the windshield and all glass components, and to wipe everything dry to avoid water spots and marks.

  • Soap

Giving your car a thorough wash using soap will remove oil, grease, and dirt. But if you fail to remove all soap from the glass, water and soap stains may settle, and these are very hard to remove. Soap stains also attract more dirt and grime, and thus, you may need to give your car a thorough wash again.

Water stains can affect the efficiency of your front and rear windshield and your car windows. These stains and spots make it difficult to see as these limits your visibility. Water stains may lead to accidents as you cannot properly check traffic or pedestrians near your vehicle. Because of these dangers, you must remove water spots on the car before you hit the road.
