How to remove hard water spots from your window


In some areas, water might contain a high amount of minerals like calcium and magnesium. This kind of water is referred to as hard water. When hard water evaporates from a surface, like that of a window, it will leave behind spots called limescale or simply calcium deposits. They can also be formed through sprinklers, showers, and even car washes.

Initially, these deposits are not very noticeable, but they build up over a certain period of time, and a thick whitish spot develops. If you don’t clean those soon enough, they get baked on by the sun over time and eventually become very difficult to remove. It ends up giving your window glass an unpleasant texture and haziness and is not recommended for your sequoia bonsai either.

Do you like your windows to be spotless? Are you worried about those hard water spots on your window? It is likely to get these spots from snow or rain. But fortunately, you can easily remove them in some very easy ways. But if you already have these stubborn spots and are looking for some remedies to get rid of them, keep reading.

Methods to remove hard water spots

Nowadays, windows can be crafted with treatments that help to prevent hard water spots. But, if your windows do not come with this feature, you can use rain repellent products, glass sealant, or even carnauba paste wax in order to prevent these spots from depositing in the first place. They will make the rainwater roll and flow off the glass instead of getting deposited on the surface. Follow these convenient and effective methods that can help you make your windows spotless:

Professional help

If these spots are way too much to clean all by yourself, or you are having difficulty taking time from your busy schedule, you should consider getting expert cleaners’ help. They do the task quickly and flawlessly and make your windows look as good as new.

Using vinegar and water

Vinegar is widely known for its cleaning properties. To use it on your window, you need to prepare a solution with equal parts water and that of white distilled vinegar. Now, spray this mixture all over the target areas and make sure to thoroughly saturate the areas that have the highest amount of buildups.

Let the solution settle for a couple of minutes and respray on the glass as it dries off. Then take a small, rough towel, wet it with the vinegar-water solution, and scrub it on the glass to remove the spots. Wipe the window to make it clean and dry with the help of a cloth or paper towel. If there are spots left behind, repeat the whole process.

Using lemon

You can use lemon to clean these spots successfully. You need to slice a lemon in half and rub it on the stained glass using a decent amount of pressure. Lemon has a natural acidity that aids in removing hard water stains without any hassle. Clean the residue with a cloth or paper towel and finally wipe it all off with a glass cleaner.

Using baking soda and water

Make a mixture of baking soda with a little bit of water to obtain a paste. Apply this paste to a cloth and then use it to scrub the window with slight pressure to let the granules of baking soda abrasively remove these hard water spots. Then rinse the glass thoroughly using water, and wipe it well with a glass cleaner and paper towel to get spotless shining windows.

Using store-bought products

If these quick home solutions do not work, you can opt for several commercial cleaners available in the market specifically for removing hard water spots. Follow all the directions mentioned on the product label to get optimum results. Finish off the cleaning process using a glass cleaner and a paper towel or a newspaper to eliminate any residue that might be left behind.

While using store-bought products, be careful to use gloves or protective gear depending on the type of chemicals present. Store it in a place far from the reach of children or pets to avoid any kind of hazard.


Spots on your windows, be it in the car or your home, can give off a pretty smudged and dirty look and can be quite frustrating for someone who doesn’t like stains. Since these deposits are not easy to get rid of using just water, you need to make sure you are investing time in the proper methods. Simply follow the tips mentioned above, and in no time, you will have pristine-looking and gleaming windows that you will love!
