VD September 09 2021

Water may sound relatively innocent to you when comparing it to different dreaded irritants like tar, overspray, debris, and squashed bugs to your car's paint. In reality, water spots on cars can damage the paint as much as the other contaminants that are already known to be troublesome. 

There are three ways through which water comes in contact with your vehicle, i.e., rain, overspray, or washing the car. Water can contain varying amounts of microscopic debris and minerals that not only dull the finishing of your car but can also harm your vehicle's paint. 

There are a few tips and methods that are able to make your car washing experience successful and much more efficient if you like to understand how to get rid of water spots on cars.

Different types of water spots

  • A regular water spot

Sometimes, the regular tap water can cause total dissolved solids to build upon the car paint. Water has naturally occurred minerals, whereas hard water has plenty of dissolved minerals like calcium and magnesium. These minerals are responsible for water sports on the car, and it can be challenging to remove these hard chalk-like deposits.

  • Bonded minerals

There are microscopic particles from different sources like smoke from the wood stoves, forest fires, construction site dust, and industrial plant emissions that are particle pollutants. These particles can accumulate on the car in the form of dust or tend to get mixed with rainwater to plague the paint’s finish.

Rainwater can also be acidic, and there can be higher amounts of sulfuric acids and nitric acid that get absorbed from the atmosphere. All these contaminants combine together to make water spots, and when the water evaporates, they leave behind the hard deposits.

  • Etching

We usually see etching when water spots get baked into the finish as a result of the direct sunlight or heat. When there is severe itching, one has to use abrasive means to get things right. One may need to contact a qualified professional because this can lead to irreparable damage if you mishandle things.

Ways to remove water spots on the car

  • Vinegar

Vinegar is a miracle substance used to clean tiles, kill weeds, shampoo the dogs, and even extend the cut flower life. Therefore, vinegar can be helpful at cleaning any water stains from the glass and body of the car. In order to wash the car, you will need white vinegar, a bucket, distilled water, a spray bottle, and a cotton towel.

You can start by putting an equal amount of distilled water and vinegar in the bottle and then shake it. The car body or the glass needs to be saturated by spraying this compound thoroughly. The remainder of the liquid needs to be poured into the bucket, and add more of it as you require. 

Lay the towel on the car area that is to be cleaned. Give it a two minutes rest, and then scrub away the strains. In the end, use the water hose to rinse the entire area with clean water.

  • Detailing clay

Detailing clay is a secret tool of professional detailers to clean water spots on cars. It is like an artist’s clay and comes in small bars that you can knead and shape just like an eraser. You can use the detailing clay with the help of the lubricant that gets included with the product. 

Detailing clay is very successful for the localized and smaller sections of the water spots. It is also great for tough water stains as it is capable of shearing off the mineral residue with force.

  • Using water spot removing products

In order to find out how to get rid of water spots on cars, a commercial water spot remover is one of the top ways to remove the localized water stain areas. There are different ingredients in these removers. The base is clean and distilled water, while the mineral oil is added as a lubricant. There are other ingredients that can act as absorbents, solvents, conditioners, and buffers.

When you re-wash and dry your car, in the next step, you have to apply water spot remover into the stippled areas with the help of a foam applicator. The spot remover is just like a car wax that can be rubbed onto the paint with a few passes. You can then finish the process by rubbing away the compound with the help of clean and dry clothes.

  • Bottom Line

You need to realize that etching might be the main reason for the water spots on cars when every other remedy fails. The etching of the paint’s surface is caused by the old and hardened water spots, and this leaves a cavity in the finishing. In order to level the finish, the abrasion of the car surface may be required, but paint can also be necessary to the difficulty level with this process. 

A few methods can be helpful when you want to know how to get rid of water spots on a car, but in the end, routine care is the best way of getting rid of these water spots.
