Things You'll Need:
- Ammonia-based window cleaner
- Paper towels
- White vinegar
- Microfiber cloth
-
Step 1
Clean your auto glass with a commercial ammonia-based window cleaner. Spray the cleaner on your glass and wipe it off with a paper towel. This will remove the surface dust, dirt and common grime, leaving only the calcium deposits.
-
Step 2
Wipe the glass clean with a microfiber cloth to remove the last traces of surface dirt.
-
Step 3
Dampen a microfiber cloth with white vinegar. White vinegar can be purchased at any grocery store. Wipe your glass with the white vinegar. Wipe especially on areas of calcium build-up, allowing the white vinegar to soak into the calcium and loosen it.
-
Step 4
Spray the glass with your ammonium-based window cleaner. Wipe it firmly with a paper towel to remove any remaining vinegar and to take off any last vestiges of calcium.
-
Step 5
Inspect your glass for any remaining calcium deposits. If any remain, repeat Steps 3 and 4.
