Glass may appear flat and smooth from a distance but is actually porous with millions of microscopic holes where dust particles and minerals from hard water can cause serious issues to your home windows if neglected. When hard water is left on glass for too long, calcium and magnesium will find their way into the pores of the glass, sometimes creating irreversible effects. Squeegee Bros offers hard water stain removal by using a polishing paste designed to remove the minerals that create these stains. The paste is applied to a non-abrasive cleaning pad and the window is lightly scrubbed. If the stain is not severe, we will remove it. To maintain your windows and prevent hard water stains, regular cleaning is essential. We recommend annual pressure washing and window washing to prevent the degradation of glass as well as situating your sprinklers to not spray your windows.
