Why Polishing Is The Best Way To Remove Water Spots

You can hardly prevent water from getting on your car, and this is the major cause of water spots on vehicles.

Mineral residues from hard water leave water spots on your car that a basic wash may not get off.

Water spots don’t look great on cars; hence, the need to remove them using the right means.

Quick Answer

As a general rule, car polish will get rid of water spots because it removes the layer of the water spot damage and leaves a fresh flat layer of paint that looks just as good as new. 

Polishing your car is one of the effective ways to remove water spots and etches caused by contaminated water.

Moreover, polishing will eliminate the water spot and restore your car’s look.

Will Car Polish Remove Water Spots?

Getting unfiltered water from rain, tap water, or well water on your car can leave mineral deposits on it that lead to water spots.

Therefore, you should be careful with the water you get on your car and clean it immediately if it gets on it.

However, things sometimes get out of hand.

Quick Answer

As a whole, car polish will remove water spots and is the most effective way to do that, polishing off the spots and restoring your vehicle to its old look. 

There are different ways to polish your car to remove water spots; however, using a machine polisher is more effective than using your hands.

It is more consistent and polishes off the spots more effectively. 

While this is great, you should be careful with machine polishing to prevent scratches and swirl marks on the spot.

However, it isn’t as serious as you may think.

Here’s how to polish water spots:

  • Wash the area you intend to work on. Spritz soapy water on the spot and wipe with a microfiber cloth.
  • Get a machine polisher with a 4-inch pad and apply a water-based swirl and scratches remover on the pad. 
  • Buff the spot with the polisher and remover, then start polishing.
  • Then use a microfiber towel to buff off any leftover polish on the car and see the difference!

Will Car Polish Remove Etched Water Spots From Paint?

Water spots are in stages, and the etching ones are the worst because they would’ve eaten into the clear coat.

Compared to just basic water spots, etching can be harder to remove, and washing or using a clay bar may be ineffective in eliminating it. 

Quick Answer

As a general rule, car polish will remove etched water spots from the paint without exposing the car’s painting. 

This will remove scratches and etched water spots, revealing a new flat layer of paint.

However, you should be careful when polishing off etched water spots to avoid exposing the car’s paint.

A way to prevent that is by using a paint depth gauge to estimate the paint thickness, which will indicate whether it is safe to continue polishing without exposing the paint.

In addition, using a machine polisher is more effective in removing etched water spots from paint than using a hand polishing pad. 

The machine will cut the etched paint away faster than the manual way.

Ensure you clean the surface you’re working on before polishing, and lubricate the polisher with water to prevent scratches and swirl marks on the car. 

In addition, monitor the surface to check whether there are no contaminants or dust on the surface that may cause scratching.

Remove them if you notice any before proceeding. 


Water spots are one of the aesthetically damaging things that can happen to your car.

If not removed quickly can become a problem.

More than focusing on removing water spots, you should work towards preventing them on your car.

Ensure you don’t let water dry off on your car.

However, if you already notice water spots on your car, polishing is the most effective way to go, but be careful with that.

Key Takeaways:

  • Polishing is the most effective way to remove water spots.
  • A machine polisher is more efficient than a hand polishing pad.
  • Use a paint depth gauge to check whether your car is still protected.
