Best Ways to Remove Water Spots on Your Car’s Exterior

After the recent rain here in Las Vegas and Henderson, a lot of car owners are noticing one annoying side effect — water spots. These stubborn marks can dull your paint and ruin your car’s finish if they’re not handled correctly.

At Royal Auto Detailing Las Vegas, we see this problem all the time, especially after storms or sprinkler overspray. The good news is, there are safe and effective ways to remove water spots and protect your paint from future damage.

Here’s everything you need to know.

What Causes Water Spots?

Water spots happen when water evaporates and leaves behind mineral deposits — usually calcium and magnesium. In Las Vegas, where our water is naturally “hard,” these minerals are found in high concentration. When the sun dries those droplets on your car, it can literally bake the minerals into the clear coat. Over time, they can even etch into the paint, causing permanent marks if ignored.

Best Ways to Remove Water Spots

1. Quick Rinse and Dry

The sooner you act, the better. If you notice spots after a rain or wash, rinse the car with clean water and dry it with a soft microfiber towel right away. This simple step helps prevent the minerals from setting into the surface.

2. Vinegar Solution

For light water spots, a mixture of equal parts distilled water and white vinegar works well. Spray it onto the affected area, let it sit for a few minutes, then gently wipe it away with a microfiber towel. Rinse and dry the area thoroughly.

(Pro tip: don’t use vinegar on hot paint or in direct sunlight — it can cause streaks.)

3. Clay Bar Treatment

If the spots don’t budge, it’s time to bring out the clay bar. After washing the car, use a clay lubricant and glide the bar gently across the paint. This removes bonded contaminants — including mineral deposits — without scratching the surface. The result is a smooth, glass-like finish.

4. Polishing and Waxing

For water spots that have etched into the paint, polishing is often required. Use a high-quality automotive polish and a soft applicator pad to gently remove the marks. Once the surface looks clear again, apply a layer of wax or sealant to protect the paint from future damage.

5. Professional Detailing and Paint Correction

If the damage is too deep for DIY fixes, don’t risk making it worse. Our team at Royal Auto Detailing Las Vegas specializes in paint correction and System X ceramic coatings, which not only remove etched spots but also create a long-lasting barrier against future staining.

We’re fully mobile — meaning we come directly to your home, office, or garage with everything needed to restore your car’s shine safely and professionally.

How to Prevent Water Spots in the Future

Here are a few simple ways to avoid water spots altogether:

• Wash regularly: Use a pH-balanced car shampoo to remove dust, minerals, and road film.

• Dry thoroughly: Never let water air-dry on your paint — always use clean microfiber towels.

• Avoid washing in direct sunlight: Shade prevents premature drying that leads to spots.

• Use filtered or softened water: If you wash at home, consider a filter system to reduce mineral buildup.

• Protect your paint: Applying a ceramic coating is the most effective long-term defense against water spotting and environmental damage.
