If you live in the midwest you know we have hard water.  Calcium and Magnesium are the dissolved minerals that cause hard water spots.  These not only occur when using tap water to wash windows they can naturally occur on the outside of your home as rain water dissolves gravel or field dust and dries on your windows. 

If you have a brick or limestone home this can occur as water interacts with the material on the outside of your home.   If you have these spots no amount of scrubbing will remove them.  Paneless windows has an owner who taught chemistry for many years and has a safe way to remove these spots from your windows. 


Once removed, our outside process uses water with no dissolved solids to keep your windows looking great year after year.
