Removing Water Spots on Windows: How to Fix & Prevent Spotting

Water Spots on WindowWater, water, everywhere, but not every drop is the same. In many areas of the country, hard water is the norm. This is simply water that has a high mineral content — mainly magnesium and calcium. This type of water is filtered and treated to make it drinkable and potable, but the softening process doesn’t remove all traces of the minerals.

When hard water evaporates on a surface such as a window, it leaves behind the minerals which dry and harden. The spots are not very noticeable at first, but after a while, the deposits build up to create a thick whitish glaze. In the early stages, these deposits are easy to get off but after a while, the sun will bake these spots onto the glass, making them hard to remove.

These hard water spots can permanently damage your windows if nothing is done to address the problem. The reason? Glass is porous and susceptible to corrosion.

If you want to try removing hard water spots on windows yourself, here are some tricks that may work:

Rubbing Alcohol: To remove mild hard water spots on windows, mix one part water with one part rubbing alcohol and apply it to the glass with a soft cloth. Be sure to dry the window when finished.

Toothpaste: Non-gel fluoride toothpaste can help remove hard water stains from windows. Squeeze a small amount of toothpaste on a soft towel and spread it over the hard water spots. Let the paste sit for five to ten minutes then wipe off with a wet towel or sponge.

Vinegar: Fill a spray bottle with white vinegar and spray the glass. Allow the vinegar to sit for a minute, respraying as it dries. Wet a towel with the vinegar and scrub the glass. Dry the window with a soft cloth. Wear rubber gloves since vinegar can be irritating to the skin.

All of the tricks mentioned may only remove hard water spots that are just beginning to appear. Removing older hard water spots on windows can be more difficult. Professionals like the experts at Fish Window Cleaning are trained on how to tackle these tough stains.
