If there is an accumulation of minerals on your windows, it can easily be addressed. There are numerous strategies for washing and expelling calcium buildup on windows that will make them appear pristine (such as diluted vinegar for cleaning). Listed below is more information about how minerals build on glass windows, the most adequate cleaning strategies for this form of buildup, and prevention techniques for the future.

What is Mineral Buildup?

This form of mineral development is customarily referred to as “hard water” or limescale. This designation notes the vast quantities of minerals in the water, as dissolved calcium and magnesium remain and settle after water evaporates. This process creates hard water stains, which isn’t ordinarily a desired occurrence. It often leaves windows perceived as grimy, unwashed and unclear when looking out of them. . 

It is fairly uncomplicated to remove these buildup stains if they haven’t had time to sit. However, if they’ve been there a while, it gives the sun time to harden the stains. This makes the calcium buildup on windows more burdensome and it takes more time to eradicate. 
Luckily, however, removing these stains is achievable with the suitable cleaning methods and materials.

Cleaning Solutions for Mineral Buildup

Whether the mineral stains have been there for an extended period of time or a few hours, they can be dealt with accordingly. How you determine to remove the hard water stain depends on your style of cleaning and the cleaning agents you are inclined toward using. The following cleaning solutions are some of the options available for hard water removal:

  • Diluted vinegar works wonders for cleaning an accumulation of calcium. When you use a vinegar and water mixture and apply it to the limescale regularly to clean, it will help stop further calcium from building. The acid in vinegar deconstructs and breaks down mineral buildup.
    After the diluted vinegar is applied and fulfills its purpose, be sure to rinse the area with normal water. 
  • A dish soap and warm water mixture will work well for a simple hard water stain, especially if it’s relatively new. Apply it to the area, let it soak for a minute, then scrub off and rinse with water. 
  • A vinegar and baking soda solution works well, as this combination can break down other chemicals. However, in order to bypass a chemical reaction, don’t blend them together or apply them to the surface simultaneously. First, apply vinegar, then let it set for a few minutes (without letting it dry on the window). Afterwards, incorporate a small percentage of baking soda to the mineral buildup by applying it on a sponge and using it to scrub.  
  • Mix baking soda and water to create a thick paste-like consistency. Administer the paste on the calcium buildup on the windows, then let it soak. After a few hours, gently rinse away with a cleaning microfiber cloth.
  • Try diluted vinegar with lemon juice for cleaning the buildup. If just vinegar and water didn’t work, try adding lemon juice. Like vinegar, citric acid from lemons will naturally assist the breakdown of calcium carbonate. Additionally, with this mixture there are two separate acids working on the calcium.

How to Prevent Mineral Accumulation

After you’ve worked so hard to clean and eliminate hard water stains off of your windows, there are ways to prevent it from building up again, which are:

  • Spray the window with diluted vinegar for limescale while cleaning, as mentioned above. This should be done pretty regularly, to remove mineral buildup before it even starts. 
  • As soon as you see a hard water stain, take care of it immediately. Don’t let it sit, and especially don’t let other stains add onto it. 
  • Clean your windows and the surrounding area frequently. A regular cleaning schedule, whether done by you or professionals, will likely prevent calcium from building.
