Hard water isn’t clean. It contains trace minerals or dirt in it, meaning what wets your car is contaminated water.
When this water dries, it leaves behind contaminants that are unsightly and destructive—water spots.
The water spots are easy to remove if you dry the car immediately. If you wait, the contaminants can get baked and hardened.
When this happens, they can damage your glass and paintwork.
Quick Answer
There are many ways to prevent water spots from forming on your car’s glass. The most popular method is to use wax or sealant. These products will make the glass surface slippery so water can’t stick. Other methods you can use include keeping the car dry, using Rain-X water repellent, covering the car, or simply keeping your car away from any source of water.
Taking care of your car involves a lot.
You can read on to find out how to protect your car against water spots.
Use Wax or Sealant
By applying a layer of ceramic, sealant, or wax coating on your car glass, it will be hard for water spots to form.
Coatings and waxes will make the paint more slippery than it ordinarily is.
The coatings help water slide off. And because a clear coat is protective, the chances of water spots forming will be significantly reduced.
When you see water beads forming tight clusters on your paint, it’s an indication that the paint is well protected.
As you drive, these water beads will fly off the vehicle, thus reducing any dirt build-up on the vehicle.
Another advantage of a protected vehicle is that it’s easier to wash or clean.
And when cleaning the car, make sure you use a shampoo designed for car washing to avoid stripping the sealant or wax.
Dry Your Vehicle Well
Some drivers may disagree, but it’s not a must to dry a car just after washing it.
You can dry your car even after you park it in a multi-story car park or your basement.
Use a drying towel to pat the car dry; do not rub or wipe it, as this might drag the contaminants over the coating and damage it.
Once you dry the car, you can use another clean towel to apply a quick detailer to it.
Wipe the quick detailer gently across the paintwork. This chemical contains lubricants that lift dirt away in a way that doesn’t scratch the coat.
If you don’t have time to dry the whole car, just dry the glass and horizontal surfaces like the boot lid, roof, and bonnet.
These are the areas where water spots are likely to form. Always remember to use soft towels.
Park Your Car Under a Shelter
Having a shelter over your car is a great way to prevent water spots.
If your car is wet and you can’t dry it, parking it under a shelter will ensure no dust or dirt settles on it.
It will also prevent water drops from getting baked onto the paint. even if the car is dry.
Parking it under a shelter is a good idea since it will protect the car from rainwater or any water spills from above.
The shelter will also protect the car against dirt and dust, both of which contribute to the formation of water spots.

Using Rain-X
Just like wax, Rain-X can prevent water spots from forming on your windshield.
This product has been used for decades for this purpose.
The difference between Rain-X and wax is that it’s in liquid form, but you can apply it the same way you apply wax, though it’s a bit easier to apply.
Rain-X is a cheap option. Unfortunately, it doesn’t last for long, meaning you’ll have to reapply it frequently.
Washing the Car Section-by-Section
One of the main causes of water spots is washing your car using well water or city water.
Water from these sources can be extremely hard because they contain minerals that can harm your wax, windows, or paint.
If you like washing your car in the driveway, you may have noticed that your car has lots of water spots.
This is because as you wash the car, you’ll be in a hurry and may not wipe away all the water until the car dries.
This means you’ll leave some hard water on the surface of your car, which will eventually turn into water spots. This may force you to wash the car all over again.
To prevent this, you can take your time cleaning the car, doing one section or panel at a time.
Then wash, dry, and wax the part before moving to the next as the part dries. It would be best to use soft water to wash your car to make things a lot easier.
Another option is to use the services of a professional detailer or car washer. These professionals will take care of all the water spots and offer the right treatment to protect your car against these spots.
They can also offer you the best tips on how to prevent water spots.
Always Cover the Car
When your car is parked, use a waterproof material to cover it.
This can be done in a commercial or residential garage.
The cover can protect your car against rainwater or any water that can accidentally splash on it.
Such a cover can be very important if you park your car in an open place with no shelter.
Stay Away from Water Splashes
Another option to prevent water spots is to try to avoid water splashes as much as possible.
Remember, water from whatever source has the potential to form water spots. Water splashes can come from anywhere.
For example, your car can get wet from sprinklers or from water splashes from your fellow drivers.
So, avoid driving near anyone using a sprinkler. You can also avoid using a sprinkler close to your car.
And when driving on a wet road, be careful about water splashes.
