Why Rain Water Stains Your Windows

Spring is right around the corner, which means spring cleaning will soon begin. While this can definitely be seen as a positive, after a long winter there is a lot of work to be done both inside and outside of your home.

While the weather in the spring is known to get warmer, a lot of homeowners will request a window cleaning, fearing the inevitable April shower.

Contrary to popular belief, rain isn’t what makes your windows dirty, and is actually very clean. In fact, rain is basically distilled water, and around the world, some window cleaners actually prefer to use rainwater.

These window cleaners use something called “rainwater harvesting”, which is especially popular in rain-soaked regions such as the United Kingdom and the Pacific North West.

So if rain isn’t the main culprit for dirty windows, who or what is to blame? The professionals at Glass Geeks are here to give you a few factors that could cause a window to turn into a water spotted eyesore:

Cleaning Window Screens

While screens are both necessary and helpful, they can be the biggest issue that a clean window will face.

Screens prevent dirt, pests, pollen, and other debris from damaging our windows. With that being said, the problem develops when the rain starts pouring.

As the rain passes through your screen, it grabs the debris and slams it against the glass. Thus, when the water dries, what is left is an unsightly dirty window.

When you get your windows cleaned by a window cleaning professional in San Antonio, or do it yourself, make sure that your screens are cleaned, as well. Be forewarned, though, as most window cleaners do not include screen cleaning and there could be an extra charge. Nonetheless, it is an absolute necessity for a long-lasting clean.

Environment

The second contributing factor to rain dirtying your freshly cleaned windows is the environment. Every part of the US is different, which means there could be local contributing factors.

For instance, in a more industrial area, acid rain is a real problem, as acid rain is precipitation that is unusually acidic, meaning it possesses high levels of hydrogen ions and a low pH.

It could have potentially harmful effects on aquatic animals, plants, and of course, windows, and is caused by emissions of nitrogen oxide and sulfur dioxide, which react with the water molecules in the atmosphere to produce acids.

If you live in an area that happens to have a large amount of carbon dioxide or other chemicals being released, then rain itself can be an issue.
