Ok, looking to offer pressure washing as an additional service to my window cleaning, and would like to know a little more before I take the plunge.
1) What can and can't you wash? Such as Decking, Tarmac, Herringbone (replacement sand needed?)
2) Is a rotary cleaner a must?
3) Does water and pressure alone remove oil stains?
4) I am sure I had so many more questions than these...sorry guys!
