When you wash your car or drive through rain, the car surfaces get wet with the water molecules. After the water evaporates, it leaves behind contaminants and minerals that cause spots and stains on unprotected paints.

Due to the more minerals, they are pretty challenging to remove, and you need a specific cleaning solution for them. Manly, these stains are caused by acid rain that contains high amounts of sulphuric and nitric acids.
Etching Water Spots

Wash the Car Properly
The best way to remove water spots from cars that are fresh and have not sat for too long is to wash them properly again! Yes, that is the best natural and easy method to get the water spots off your car after a wash.
Sometimes we see that after washing the car, we get busy arranging the stuff we used to wash the car, or we take a rest for some time before we dry the vehicle. And in the meantime, the water droplets get dried, and the white spot starts showing.
It is because these spots have not sat for too long and are fresh; you can easily take them off with another wash. This happens mostly when the car is washed under the sun or has not been coated with wax or sealant.
While washing, you must ensure there are no dust particles on the car’s surface; otherwise, while rubbing, you may cause scratches and swirl marks on the surface, making it worse.
While removing water spots on car, be gentle and use a microfiber cloth to dry soon after washing again. This method works fine only when the spots are fresh. But if this doesn’t work, try out the next solution.
Give the Car a Vinegar Rinse
Using vinegar to get rid of water spots on car is one of the most effective home-based hacks that you can apply to keep your vehicle from getting damaged due to the water spots. Vinegar is easily available in most of our homes, and you can use white vinegar to eliminate the marks caused by tough minerals or calcium carbonate.
It is because vinegar contains natural acetic acid that helps in dissolving the calcium carbonate or other minerals present in the water droplets that cause the hard spots on the car’s surface.
Mix the vinegar solution with water, spray it on the surface where there are spots, rinse and dry. The process is easy, but if not done correctly, it can cause more damage to the car paint than keeping it safe from water spots.
It is a cheap and natural method to get rid of water spots from your car paint surface. Drying the surface and then applying wax or other coatings is better to keep it safe from further spotting. However, the very hard water spots on car won’t come off with just vinegar.

Many of us raise our eyebrows while thinking – Will clay bar remove water spots? It will indeed, but only when the water spots are not etched. The clay bars are effective in cleansing off the other hard water spots efficiently. It might be an aggressive method to use clay bars to remove water spots, but it is required in cases where the spots are too complicated.
A clay bar has the capability to remove tough minerals and calcium carbonate from the car paint surface, and when done right, it does not even harm the clear coat. Because clay is an abrasive compound, you need to be careful while using it.
Use a lubricant or detailer along with the clay bar, glide it across the surface where there are spots, be gentle while rubbing, wipe the surface, dry it using a microfiber towel, and you are done!
Always remember to use the detailer spray or lubricant whenever you are rubbing through the surface to keep it wet; otherwise, the clay bar can cause the paint to be damaged.

These commercial water spot remover products contain distilled water and mineral oil as base and lubricant, respectively.
In addition, the remover also contains solvents, absorbents, buffers, and conditioners that make the spot removal process even more accessible. Not only that, these removers work effectively on all kinds of water spots and also leave a glossy finish after you are done.

Apply a Paintwork Cleanser
The paintwork cleanser is not only used to remove water spots from car paint. As is evident by the name, it is also used to remove other contaminants, strip waxes, and remove water spots simultaneously. Though the paintwork cleansers are pretty effective in removing the hard water spots from the car paint surface, they might not be as good at removing the etched marks on the car.
But if you want an easy and effective way to remove stubborn water spots on your car, applying a high-quality paintwork cleanser such as P21S Gloss-Enhancing Paintwork Cleanser or Wipe Out Surface Cleanser Spray can help you immensely.
Applying the paintwork cleanser formula is very easy. You can use a microfiber applicator or soft foam to apply the cleanser with bare hands. You can also use a dual-action machine polisher if the stains are too deep.
First of all, apply a thin layer of the product on the surface paint, leave it to dry as per the instructions written on the product (typically 5-15 mins), then buff the cleanser using a soft microfiber towel, and you are done.
It is a pretty simple and less time taking process that you can rely on to get rid of the hard water spots on your car surface. However, as already mentioned, it is not the best way to remove hard water spots from car that have etched the paint surface’s clear coating. Try the next methods if that is the case.
Polish the Area
You must only resort to this method when the water spots won’t come off car using the previous methods. This is the most aggressive method that you must only use when the car surface has etched water spots, and it doesn’t come off using any other methods.
Polishing the car’s surface means removing a layer of the car’s clear coating. For those who don’t know, the clear coat of the car surface is applied externally to protect the base coat of the car paint.
When a part of the clear coat is removed, it becomes thinner, and the base coat might be more prominent towards the damages. But in case the water spots do not come off using any other method, you have to pull through this method.
Be very careful while doing it because one mistake can cause permanent damage to your car paint. However, if you do the polishing by yourself using a microfiber polishing pad or foam, the process can be less risky than using a machine polisher.
It is the best way to remove water spots from car paint that are etched on the surface and won’t come off easily. Take professional help in case you are worried about the result.
Use a Rubbing Compound
After going through all the above methods, you might have the question – Will rubbing compound remove water spots? As simple as it sounds, using the rubbing compound technique is not so simple!
In fact, it is one of the most effective methods to be used when the watermarks are not only etched but are also very severe. And when they are severe, your car paint is at high risk because any removal process can damage them even more!
Applying rubbing compound is almost the same as the polishing method, but unlike polishing compound, rubbing compound is more aggressive in nature. The rubbing compound also removes a layer of the clear coat of the car paint, but it does faster than polishing which makes the car paint prone to damage.
It is advised to use a machine polisher during compounding, again unlike the polishing method. It will be even better if you can just take the help of a professional.
Since the rubbing compounds are more abrasive in nature, they can leave a hazy paint layer, and you must use coating products that make the surface glossier after the compounding process is over.
Always remember, this is the last option you should apply only after all other methods fail to deliver results. It is an easy way to remove water spots from car that does not go by any other methods!
