How to Clean Air Conditioning Water Stains on Car Windows?

First, clean and dry the glass, ensuring no sand or dust remains on the surface. Next, shake the car glass cleaner well and apply an appropriate amount to the gray side of a sponge. Then, use the sponge to make small circular motions on the glass surface, spreading it evenly. After wiping, rinse the glass with water and dry it with a towel to remove the air conditioning water stains.

Water stain marks on car windows are usually mineral residues left behind after rainwater or air conditioning condensation dries, sticking to the surface like scale. I often use simple household methods to deal with them: pour some white vinegar onto a soft cloth, apply it to the stains, wait for five minutes to let it dissolve the minerals, and then rinse with clean water. If the stains are stubborn, mix baking soda and vinegar into a paste, apply it, and wait a bit longer for easier removal. Avoid using hard cloths or scraping tools to prevent scratching the glass. For prevention, park away from trees or rain-prone areas and regularly clean the wipers and water trough. Clean in the shade to avoid direct sunlight. Applying an anti-stain film can also save trouble by preventing new stains from forming, ensuring safer driving.
