How to Remove Water Spot from Car Quickly?

From the surface, water spot looks like a pretty harmless contaminant. The fact that it originated from water gives the impression that it doesn’t pose any threat.

However, water spots have the potential to damage car paint. If you’re looking for how to remove water spots from a car, it’s important to acquaint yourself with the various types as well as preventive measures.

How to Remove Water Spots and What You Will Need

The most common thing among car owners when they see water spots is to assume a simple wash and dry will do. Yes, you probably know how to wash your car by now but getting rid of water spots requires extra effort. But, we’ve come up with three effective methods of getting rid of the spots effortlessly.

1. The Vinegar Method

The Vinegar Method

White vinegar is a form of acid that works great in removing hard water spots. The minerals present in hard water have high PH, which reacts with the rather low PH of vinegar, thereby causing the spots to dissolve.

  • Getting rid of spots with vinegar commences with dissolving the solution in distilled water.
  • Take a bit of the vinegar solution and apply it to a portion of the body with the sponge. Apply the solution on the water spot and allow it to remain for up to 2 minutes, so the mineral loosens up.
  • Continue to apply on the affected areas and gently wipe the water spots off after a few minutes before rinsing with clean water
  • Dry with a towel and ensure it’s done lightly. Do not be aggressive about removing the spot as your paintwork might be affected.

2. Clay Method

Clay Method

Clay can be very effective in removing water spots and other contaminants. However, it only works in cases where the contaminant is on a glass surface such as the windshield and windows. So, clay does not work for all types of water spots, especially in the case of mineral deposits.

  • First, start off by lubricating the affected area with Clay lubricant to minimize scratches as the clay bar moves around the surface.
  • Apply and move the clay around the affected area to get rid of contaminants.
  • Continue working the clay around the surface until it slides freely without feeling gritty around the contaminant.
  • When you’re finished, wash it off with water, followed by a clean microfiber towel.

3. Water Spot Removers

However, it’s recommended you test on a spot before rubbing it all over the affected area.

What Are Water Spots

Waters are very easy to recognize and mostly occur due to evaporation of water from the body of the car leaving behind sediments. This contamination could be from chemicals, dirt as well as minerals. It’s these sediments that sit on the body of your car once the water evaporates.

Luckily, mild cases of water spots can be eliminated during a quick washing routine with several household materials. However, severe cases might require the help of a professional or risk damaging your car body.

Go through this guide to know the major factors responsible for water spots.

The Different Types to Know

There are several types of water spots, and they’re majorly caused by the presence of solid minerals in varying quantities.

Regular Water Spot

Regular Water Spot

This is the most common types of water spots and is caused by the presence of totally dissolved minerals on car paints. Most times, hard water contains undissolved minerals that easily stick to the surface of the car during Washing.

Bonded Minerals

Bonded Minerals

Pollutants in the form of smoke, dust and forest fire can combine with other particles which falls on your car in the form of dust or dissolve in rainwater to form a plague. Normally, rainwater is acidic to some extent. It contains a high amount of nitric and sulfuric acid absorbed from the atmosphere.

These minerals combine with water to create spots which are hard to clean off after the water evaporates. These deposits bond to your car paint and forms a permanent coat if not removed on time.



This occurs when water spot combines with your car finish due to excess heat. In the worst cases, you might need an abrasive to correct the situation. When Etching occurs, it’s important to reach out to a professional as handling it yourself might lead to serious damages to your car body.

Preventing Water Spots When You Wash Your Car

  • It’s possible for water drops to develop in your car even when you wash. This is why we recommend you avoid washing under direct sunlight. A shaded area like your car garage help keeps the body of your car wet during the whole process, so some water doesn’t dry on the surface.
  • Also, it’s preferred you use a washing mitt that won’t grind debris on your car. This is why you should use an all-purpose rinse bucket, so it keeps the mitt free of dirt as you wash. Also, ensure you replace dirty water as you wash.
  • You might want to wash the wheel first before going higher up. This is because washing the body while the wheel is dirty might cause dirt to splash on it. What’s even more important is having a pair of towels nearby. Air drying is just a way of inviting water spots as the air is unevenly distributed across the body.


One thing to note if you want to know how to remove water spots from a car is that when all the methods above fail to yield any result, this could be a sign of Etching. This occurs typically when water spots are left on a surface for long making it a bit difficult to remove. Professional help might be what you need at this point.
