How to Remove Water Spots from Car Windows and Windshields

Understanding Water Spots

Water spots are residues left on surfaces, particularly glass like a windshield, resulting from the mineral content present in water. When water containing minerals such as calcium and magnesium evaporates, these minerals remain behind, forming spots on the windshield. They are commonly seen after rain showers, washing your car, or exposure to sprinklers or irrigation systems.

The mineral deposits accumulate as the water dries, leaving behind noticeable spots that can obscure visibility and diminish the aesthetic appeal of the glass surface. Whether from natural sources like rain or artificial ones like automatic car washes, the outcome is the same: stubborn spots that mar the clarity of your windshield and hinder your ability to see clearly while driving.

DIY Methods

There are a few popular DIY solutions for removing water spots from car windows and windshields :

Vinegar Solution

Mix equal parts of distilled water and white vinegar to create a powerful cleaning solution. This concoction serves as a natural solvent to dissolve mineral deposits. Apply it using a microfiber cloth, gently rubbing the affected area. You’ll notice the water spots fading as you wipe away the solution.

Baking Soda Paste

Mix 1 or 2 tablespoons of baking soda with water until it forms a paste. Add more water as needed. This baking soda and water mixture forms a paste, creating a gentle abrasive that can break down the mineral deposits. Spread the paste over the water spots and use a soft cloth to scrub gently. Rinse the area and wipe off any residue, revealing a cleaner surface.


For a natural and effective solution, reach for a fresh lemon and cut it in half. Apply gentle pressure as you rub the lemon onto the glass surface. Thanks to its natural acidity, the lemon effortlessly eliminates hard water stains. Use a soft cloth or paper towel to clear away residual lemon juice.

Complete the process using a glass cleaner spray and wipe it down with newspaper (or a microfibre cloth if you have one handy) for a streak-free shine. The ink and paper fibres from the newspaper create a slightly abrasive surface that helps to remove dirt and grime from the glass.

Preventing Water Spots

Preventing the reappearance of water spots is crucial for maintaining visibility on the road and the pristine appearance of your car. Here are some tips for preventing and removing water spots :

  • Regular Car Washing: Make it a habit to wash your car regularly using a pH-neutral car wash shampoo. This helps remove dirt and contaminants that contribute to the formation of water spots.
  • Thorough Drying: Always ensure thorough drying, especially of the windows, after washing your car. Wiping down the surfaces prevents water spots from forming, keeping your glass clear and spot-free.
  • Apply Protective Coatings: Consider applying protective coatings or sealants to your car’s surfaces. These coatings create a barrier that repels water and prevents mineral deposits from adhering, thereby maintaining the shine of your vehicle even after exposure to rain or washing.
  • Avoid Water Overspray: Whenever possible, steer clear of parking your car near areas prone to water overspray, such as sprinklers or irrigation systems. Minimising exposure to overspray reduces the risk of water spots forming on your car’s surfaces.
