Lime deposits, for example, can develop as the result of sprinkler over-spray. When sprinklers repeatedly spray a building’s windows, and the windows go un-cleaned or unattended, the water can create mineral deposits that leach onto the glass. Once this happens, the bright white surface deposits can be removed, but the dull grey spotting that takes roots underneath the glass’s surface is permanent. The permanent spotting can only be removed by restoring the window and replacing the glass itself.
