Water Spot Remover from Glass Buyers Guide
Before you go off and start buying products, there are a few things that you need to know about hard water spots, the removal products, how to get water spots off car windows, removing water marks from mirrors, and more.
Understanding Hard Water Spots
Something you might be wondering is what hard water spots actually are. Now, no these are not just spots caused by water drying on the surface. Hard water is something very specific. Water hardness is defined by the amount if dissolved minerals in the water, mainly calcium and magnesium. The more of these minerals are present in water, the harder the water is.
The harder water is, the more stains it will leave on a variety of surfaces. Those white stains that look like dried, white water, those are hard water buildups. They may also be salt buildups, which is the case if you are driving in the winter in areas where they use lots of road salt. The main point here is that hard water leaves white stains and streaks behind, ones that can be very difficult to remove.
Even if you don’t really care about how bad these water spots look, the aesthetics aren’t the problem. When hard water deposits are left to grow on your car, they can really etch themselves into the paint, thus causing damage to the paintjob on your vehicle. Over time, it can also make it much easier for rust to form and the car to start corroding.
How to Remove Water Marks from Glass or Window
Whether it’s about removing water stains for exterior windows or how to get mineral deposits off glass in general, the process is always going to be more or less the same. Now, it does depend a little bit on the exact product you are using, but in general, the process is going to be very similar across the board. Follow the steps as outlined below.
- Make a mixture of half water and half vinegar.
- Apply the mixture to the surface and use a microfiber cloth or sponge to scrub.
- Rinse the glass very thoroughly.
- If there are still hard water spots remaining, use one of the hard water spot removers we have reviewed today.
- Use a cloth, sponge, or applicator pad to apply a small amount of the product as directed, and rub it around on the surface for as long as directed on the product’s instructions.
- You then need to wipe the cleaner off of the glass or window, and you may also need to do a rinse job afterwards.
