Within this page you can find out more information about Home Window Cleaning, We also welcome Commercial/Industrial Cleaning and you can find out which areas we serve. We refuse to use chemicals or soap, because chemicals and soap tend to leave residue on "clean" windows, giving dirt and grime something to cling to. This can make windows dirtier over a shorter period of time. At RDS, we use filtered rain water as much as possible, and because we use this filtered water, many of our customers claim that when we clean windows, they stay cleaner for longer.
