Hard-Water Stains – Residential Windows

We have all seen them, and your typical window cleaning methods don’t seem to remove them – hard-water stains. In this post L.A. Elite Window Cleaning will go over what causes these, how you can remove them yourself, and what can happen if they are not taken care of in a timely manner.

Let’s jump right into this and see what causes these buggers.

What Causes Hard-Water Stains

Hard-water stains can be caused by a combination of things, especially while living here in Southern California. Salt and minerals can be carried in from the winds passing over the ocean, acid rain, sprinkler systems, or by varies airborne contaminants here within LA’s bustling urban setting. Over time these contaminants can build up on a buildings exterior, but most noticeably the windows. This build-up can be seen as patchy white areas or cloudy spots similar to those seen on shower doors.

How-To Remove Yourself

There are specialty cleaners out there; however, we wanted to go ahead and provide you with a cheaper solution using typical household items:

  1. Fill a spray bottle, half water and vinegar (lemon or lime juice works as well);
  2. Spray solution on glass;
  3. Spray a towel with same solution;
  4. Lightly scrub glass with solution dampened towel;
  5. Allow to sit for a few minutes;
  6. Remove with a clean towel;
  7. Repeat if necessary.


Top Reason To Remove Hard-Water Stains

The minerals that are build up on the glass are not only visually unappealing, but they are corroding your glass as well. You must keep in mind that glass is not as smooth as it appears and feels. If you were to highly magnify glass you would see that it is actually quite a porous material. If these stains are not removed in a timely manner the glass may permanently appear stained or scratched. If the stains have been on the windows for quite some time you may want to give a professional, like us, a call to prevent further damage.
