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%!

"Excellent service and product! They checked in with me every few weeks while we were waiting for the order. I was impressed with Sam, who measured my windows and headed the installation crew. He was respectful and patient with his team. They cleaned up after themselves. Before the new windows I had huge windows that didn’t open. Now I feel much safer and get better temperatures in those rooms."

"My experience with Anderson Renewal was amazing! From the first meeting with Miranda to choose my windows and doors to the installation provided by Tim and his crew was a pleasure! I just bought a home built in the 1960's that needed new windows and a new double front door with sidelights. As everyone knows Anderson Windows are great, but it was the people I interacted with from Anderson that made it such a great experience. It took three days for the windows and door to be installed and they "worked" every minute they were here. My huge front door took most of the day to install because they had to put in a new header and other improvements to make it fit! They even put up new drywall on the inside. Many people in the neighborhood have stopped by to comment on my beautiful front door! I think the crew left my house cleaner than it was before they started! Constantly cleaning up after themselves. I am thrilled with my windows and feel lucky to have met the team at Anderson."
