What to do if there are water stain-like marks on the car window that can't be wiped off?

[SanKendra]

Hard water stains are mineral deposits formed by elements in the water, mainly calcium and magnesium. Here are some solutions: 1. Method one: Use a vinegar solution. Fill a spray bottle with equal parts water and vinegar. It's best to use pure distilled white vinegar. Dry with a clean, dry towel or paper towel, or use a rubber squeegee to remove the water. Do not let the vinegar solution or water air dry on the glass surface to avoid leaving more stains. 2. Method two: Use other natural products. Replace vinegar with lemon juice. Lemon juice, like vinegar, is acidic and very effective at removing water stains. Add a few drops of essential oil to the water and gently wipe the glass with a sponge or towel. 3. Method three: Use an abrasive cleaner. Purchase an abrasive cleaning powder. The main benefit of abrasive cleaners is that the particles inside provide a slight scrubbing action.
