How to Remove Alkali Stains from Car Windows?

[CharlieLynn]

To remove white alkali stains from glass, you need to prepare the following materials: a scouring pad, a bottle of white vinegar, and two pieces of paper towel. Pour an appropriate amount of white vinegar onto the scouring pad. Use the scouring pad soaked with white vinegar to gently but firmly scrub the white alkali stains on the glass. After 4-5 minutes, use the paper towel to repeatedly wipe the areas with white alkali stains on the glass back and forth.
