After window washing, you might notice tiny specks of residue or streaks on the glass. If the surfaces are still grimy after you use detergent, the tough-to-remove spots could be caused by hard water. This means limestone, calcium, magnesium, or other mineral deposits in the liquid are sticking to the glass when the windows dry. To restore the quality of your investments, below are useful tips on how to wash away hard water spots and prevent them from returning. 

How to Remove Hard Water Stains on Windows

Although detergent might not remove the mineral residue on windows, several common household products will dissolve the grime. After window washing, spray vinegar, window cleaner, or lemon juice on the spots and then wipe down the surfaces with a squeegee brush. You can also use a cloth; just make sure the material is non-abrasive to keep from scratching the glass. Avoid washing windows on sunny days, as the liquid will dry too quickly on the hot glass and cause additional streaks.  

How to Prevent Spots in the Future

Window washing with hard water won’t only damage the glass; the minerals can also accumulate in pipes and the drain lines of water-operated appliances, causing major clogs. Installing a water softener will remove the minerals to prevent stains on windows and additional problems. Deposits in rainwater can also stain windows, so place awnings over the fixtures. Hard water from sprinklers can also splash on the fixtures, so make sure equipment doesn’t spray near the glass.
