Calcium removal the 100% natural way.

ABC Window Cleaning Specialists perfects a 100% natural way of removing calcium from glass. Over the years I have been asked to remove calcium from windows more times than I can count because the scheme water and some of the ground water around Perth is full of calcium.
For those who are not familiar with what calcium can do to windows it is the white film or build up that is shown in the before photo attached to this article. Calcium deposits when sprinklers spray water on the windows. The sprinkler does not even have to be spraying directly on the windows. All that has to happen is the mist from the sprinkler drift onto the windows and over time layers of calcium will build up forming the telltale white fog on the window.

When the water drys the calcium is left behind, attached to the window and sets hard as rock. At first you don’t notice any thing because the amount of calcium is so small. Over some weeks or months the build up becomes visible and then you get that classic calcium stain which is impossible to remove with conventional cleaning.

There are a number of commercially available products to remove calcium but they contain Hydrofluoric acid. The problem with that is that using hydrofluoric acid regularly will etch the glass  removing the smooth finish or glaze leaving your glass looking like it has a bad buildup of calcium anyway. Once the glaze has been removed there is nothing you can do to get it back. The only way to get a window to be clear again after the glaze has been removed is to replace the window.
Even worse than removing the glaze (because at least the window can be replaced) is hydrofluoric acid is a known carcinogen so it will remove the person who works with it. There are also several other acids that in combination will remove calcium but again they are so toxic I will not work with them. There is also a product sold in Australia at least (with a 3 letter name) but again it has gluconic acid, lauramine oxide, Propylene Glycol n-Butyl Ether and phosphoric acid, quite a cocktail. Don’t get it on you or breath in the fumes this one is no better than hydrofluoric acid and is sold in most hardware stores.
By the time calcium has built up on the windows for you to see it is so hard that using a scraper to remove it is out of the question. I have see several windows where some one has used a scraper to try to remove the calcium and the scraper had not even made s dent in the problem. Even worse is that because the calcium is so hard and rough that when the scraper is run up the window it skips along the rough surface which can result in the glass being scratched. Then you have calcium and scratches on your glass.
I have developed a way of removing the calcium from the class that does not involve scratching the windows or harsh chemicals. In most cases one application of my system and the calcium is gone. However if the calcium is a very thick build up it may take two or three application unlike the commercially available chemicals mentioned above which will remove the calcium in one go but will probably remove your window cleaner too.
