Hard water refers to the calcium and magnesium in water. These are minerals that are in the water. When you wash your car and the water dries the water leaves the minerals on your car’s paint, leaving behind water spots.
As noted above, there are some precautions that you need to take when washing your car with hard water. Remember, it’s not bad to get hard water on your car, it’s bad to let it dry.
So go ahead and fill up your buckets and get ready to wash your car. Just don’t forget your drying towel.
When you wash your car you will have to work one panel at a time. Wash one panel and then dry it, and then move onto the next one. This is easier if you are using the two bucket method or doing a rinseless wash. Avoid using the hose if you can.
If you find that the water is drying before you can dry it off then you need to work on a smaller section at a time.
Tip: use a microfiber towel specifically for drying. I prefer one with a waffle weave patter.
You will soon learn that the sun is going to be your enemy. Try to wash your car in the morning or the evening when it’s not too hot. Look for shade.
Another option albeit a bit more expensive is that of a water deionizer. A water deionizer is a machine that filters out the minerals so that you can have a spot free wash.
These are popular among detailers. These typically range from a a few hundred dollars to a few thousand dollars. It is a bit pricey but it can get the job done.
After you wash your car you should apply a form of protectant. You can apply a wax or a sealant. These will make your car hydrophobic (almost like water resistant) which means the water will slide off the car better. This means that there will be less water sticking to your vehicle which will hopefully leave less water spots.
