Understanding All About Hard Water Spots


Water spots come in different forms and show on your vehicle differently. The most common and frustrating are the spots that appear on the paint and the glass. Let us take some time to understand what these spots are, how to remove them and various ways to avoid them.

How Do Water Spots Occur?

These are spots left on the paint or any surface when you leave the hard water to evaporate. The cause is usually a result of using hard water or exposing the car to hard water regularly.

It might also come about if the car is not dried properly after a wash, or if you go and park the car near a sprinkler. It also occurs when you leave rainwater on the surface to evaporate on its own.

Things get worse when the water that is in use contains a corrosive substance that can etch the surface of the car, creating a depression. If not addressed, this depression becomes worse over time, because the hard water continues to pool into the depression and continues etching into this same spot. The spot occurs because hard water evaporates and leaves behind minerals that dry up and harden making it difficult to remove them. No sealant, wax or paint is impervious to these spots.

These spots are hard to avoid unless you know where the source is.  They are hard to remove; you might end up scratching the paint off your car, and still, they will not go away.

So, what are the reasons that this spot is on your car?

Sprinkler System

If you stay in an apartment and park your car in a lot that has sprinkler systems, you might be a victim of the spots. This is the most common and yet severe source of hard water spotting. The sprinkler continues to sprinkle water on the car day in and day out, leading to numerous spots all over the vehicle.

Automated Car Wash Machines

Many of these machines claim to use soft water to clean your vehicle. This is not true in many situations. Many of the companies that offer this service still use hard water for the task; oblivious to the damage it causes the paintwork.

Additionally, the blowers that are at the end of the tunnel do not get out the water that is trapped in the jambs and the seams, and this water leaks out to the body of the car and then hardens.

If you go for an automated car wash, then take some time to towel dry the car by yourself or insist on having the car towel dried. This saves you a few blushes down the road. Just make sure the car is dried using clean towels so that you don’t end up scratching the paint.

Washing Your Car

Truth is unless you have someone to help you and a pressure washer, then you will not be able to towel dry the car to the extent that it does not experience hard water spots. However, with the right equipment and supplies, you can do it on your own. One way to do this is to make sure you have a water softener from SoftWaterFiltration to help you get the right water for the task.

A pressure washer helps you clean the car faster than you would manually. Get a washer that suits your needs to enjoy the benefits of washing the car on your own.

How Do You Prevent Hard Water Spots

Not getting your car wet is not a solution to this issue because occasionally you have to wash the car. What you need to do is use a good sealant or wax the vehicle so that it does protect the underlying paint from coming into contact with hard water.

Secondly, make sure the car is clean all the time. Remember that it is not the water that leads to these spots, but the fact that you leave the water on the car surface long enough for the minerals to harden.

In Closing

Hard water spots are a nuisance and become costly if you watch them grow. Make sure that you follow these simple steps to keep the car free from spots.
