Worried about the rain? Worry no more!
A common misconception is that rain causes windows to dirty and spot. Not true. As discussed and dispelled in Good Housekeeping magazine and Martha Stewart Living, rain does not cause windows to dirty or spot.However, it is a commonly held belief that windows should not be cleaned when it rains because the rain will just make them dirty again. Is this really a fact? Does the rain make my storefront or building windows dirty?

When windows are clean the rain will simply run off and the glass continues to remain clean. Rain water is pure water. You can put it directly into a bucket and clean windows with it!
So, with that, we will give you the most generous rain guarantee we've seen in the marketplace yet for commercial storefronts.
