Causes Of Hard Water Stains
Hard water stains form on auto glass when minerals in water dry. These stains look cloudy and are hard to remove.
Knowing what causes these stains helps you prevent and clean them better.
Mineral Deposits On Glass
Hard water contains minerals like calcium and magnesium. These minerals stay on the glass after water evaporates.
Over time, these mineral deposits build up and create white or cloudy spots on your auto glass.
- Calcium carbonate creates rough, chalky stains
- Magnesium leaves a white, powdery residue
- Other minerals can add to the hardness of the stains
Common Sources Of Hard Water
Hard water comes from natural sources and household use. These sources bring minerals that cause stains.
Knowing where hard water comes from helps you avoid stains on your car glass.
- Tap water in many areas contains high mineral levels
- Rainwater can pick up minerals from soil and air
- Washing cars with hard water leaves mineral deposits
- Sprinklers and hoses often use hard water
