Water spots on your car’s windows and windshield can be a real headache. They not only compromise visibility and make driving less safe, but they also detract from the overall look of your vehicle.

Whether these water spots result from rainwater, automatic car washes or irrigation systems, residue can accumulate over time. This residue leads to reduced driving visibility and an unsightly, rough appearance. But don’t worry; this comprehensive guide will teach you some foolproof ways to bid farewell to water spots from car windows and windshields.

If you want to see your car’s windows and windshield shine like never before, book your appointment with Espresso Car Wash online. Our experienced technicians can restore that shine to your vehicle’s exterior and interior.

Understanding Water Spots

What are water spots and why do they form on a windshield?

The main culprit behind water spots is the mineral content of water. Water from rain, sprinklers, or washing your car can contain high levels of minerals such as calcium and magnesium. These deposits accumulate on your windshield as your car dries, leaving behind those unsightly spots that are especially noticeable on glass and glossy paint.

It is also worth noting that if you park your vehicle next to sprinklers or irrigation systems, overspray can contain minerals that contribute to the formation of these spots. So whether you’ve spotted them after a rain shower or a trip through the car wash, the result is the same: dirty windows that make it difficult to see the road in front of you.

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

Prevention is often the best solution. To avoid the return of water spots:

  • Wash your car regularly – Ensure that you regularly wash your vehicle using a pH-neutral car wash shampoo to remove dirt and contaminants contributing to water spots.
  • Dry your vehicle after washing – Always wipe down your windows after cleaning your car. This simple step helps prevent water spots from forming, ensuring your glass stays pristine.
  • Apply protective coatings or sealants – These create a barrier against water spots, allowing your car to maintain its shine even after rain or washing.
  • Avoid areas with overspray – If possible, avoid parking your car near sprinklers or areas with frequent water overspray.
