Types of water stains

Before you clean your car, you should know the different types of stains to help you remove them faster. The following are the most common water stains.

Regular water spots

Your tap water has minerals that can destroy or ruin your car’s paint. These minerals cause water spots, a hard chalk-like substance, also known as limescale, which is difficult to remove.

Bonded minerals

These are the particle pollutants that come from forest fires and smoke, as well as carbon emission from vehicles, industrial plants, and construction sites. These tiny particles can just be dust on your car or they can destroy your car’s paint job.


Etching stains are stains that have bonded to the paint surface and are hard to wipe away. They could be caused by something like bird poop or stains from rain that has evaporated and been exposed to high heat or direct sunlight. If the stain becomes severe, you need to use abrasive methods to repair the damage. You need to hire a professional to fix this problem, as one wrong move will lead to irreversible damage.
