Maintaining a clean exterior is far more than just an aesthetic choice. While rain may take care of some external dirt and grime on windows, it won’t eliminate all grime or dirt which can lead to costly expenses in repairs to casing or sashes down the line if not taken into account now. 

By keeping your windows clean, you can maximize the beauty of your commercial building’s exterior. Without regular cleaning, thick films will build up on glass and impede views from both indoors and outdoors!
