When the water in your area happens to have a high content of minerals such as magnesium and calcium, they can be a bit hard to clean off on some surfaces. This type of water is called hard water, and when it evaporates from a glass surface such as one from your windows, it can become difficult to remove over time.

To help you out, our window and door replacement team at Renewal by Andersen® of Seattle shares an effective method below.
How to Remove Hard Water Stains
When hard water evaporates from your windows, it will leave spots known as calcium deposits or limescale. They won’t be noticeable at first and can be easy to clean off, but when they get baked by the sun over time, they become difficult to remove. Eventually, it will give your windows a rough texture and unpleasant haziness.
To effectively get rid of the hard water stains, you’ll need to prepare a mixture of half water and half vinegar. Soak a towel in the solution then press it onto the rough stains of your affected windows for about a minute or two.
Upgrade to Self-Cleaning Windows
Our quality windows and hinged patio doors are well-known to many homeowners, as our products give the best balance between beauty and performance. In fact, there’s no need to make an effort when it comes to cleaning our windows, as it features a self-cleaning titanium dioxide exterior coating that prevents watermarks
Titanium dioxide is a white and powdery titanium compound that’s normally used to give that shine on paint or toothpaste. It’s essentially the white in white paint, but since we only apply a very thin layer of coating on our windows, it’s practically transparent on the glass surface while only reducing light passing through the glass by about five percent.
If you’re looking to have new windows or gliding patio doors installed, then our team at Renewal by Andersen of Seattle can help you out. To get started, call us at (206) 777-0954 or by filling out our convenient online contact form. We serve our customers in Seattle and surrounding areas!
