Dealing With Hard Water Stains on Your Windows

Have you ever noticed hazy stains on your windows that don’t seem to come off easily? This indicates your local weather has hard water, which is a mixture of water and a high content of minerals, such as magnesium and calcium. Hard water makes it a bit difficult to clean off on some surfaces, especially when it evaporates from a glass surface like your windows. 

Water Stains on Your Windows

Here’s how to clean hard water stains.

Removing Hard Water Stains

Hard water that evaporates from your windows will leave spots known as calcium deposits or limescale. These deposits won’t be noticeable at first and can be easy to clean off as long as they don’t sit on the glass surface for too long. Otherwise, leaving them under the sun for some time makes them difficult to remove. The accumulation of these deposits will eventually give your windows a rough texture and unpleasant haziness.

One effective method to get rid of the hard water stains involves preparing a mixture of half water and half vinegar. A towel must be soaked in the solution and then pressed onto the rough stains of your affected windows for about a minute or two. Keep repeating this process until the stains are cleaned off the surface.

Upgrade Your Windows Today

If you’ve been having hard water stain problems on your windows for a long time, then it may be time to upgrade to better-quality windows. Our top-of-the-line energy efficient windows are made with materials that ensure they’re easier to clean. This is because our window products feature a self-cleaning titanium dioxide exterior coating that prevents watermarks!

The titanium dioxide coating that we use consists of a mostly white and powdery titanium compound. It’s essentially the white-in-white paint and what’s normally used to give that shine on paint or toothpaste. But we only apply a very thin layer of coating on our windows, so it’s essentially transparent on the glass surface. This coating hardly affects the amount of light passing through the glass as well, reducing it by only about 5%!

As a top window installer in the area, Renewal by Andersen® of Southwest Missouri is your best choice for the job. You can reach us at (417) 268-9301, or you can contact us online through our convenient form.

"After years of watching the wind move my drapes and hours of difficult cleaning, I decided to get new windows. I went with Renewal by Andersen because of the great reviews and quality. From Brent who did the consult, Gideon who did the measuring, to Jason, Josh, and I apologize I can't remember the third installers name, this is the most professional company I've ever worked with. I own a 1994 double wide mobile home, so everything in this place is hard to work with. I had a bay window, 6 double hung, 2 awning, and a front door replaced.. They said it would take 2 days and they were done on time! I did have second thoughts about doing this mainly because of the cost, but once it was done, I was very happy I did this."
