@Fredled, you might want to rethink that. Go to http://pressurewashingresource.com/
and check out the long list of problems, the need for more and more equipment, trucks, trailers, etc. Get a feel for how dirty PWing can be. And while there are more people cognisant that they need PWing than are aware of their dirty windows, most folks will rehire you in 6 or 12 months to do their windows again. REPEATS ARE SWEET!
Right now I’m doing more PWing than windows, and I am eager to turn that around when it gets a little colder. I’m weary of getting soaked, using strong chemicals that ruin my nice shirts
and who knows what long-term impact they will have on my health. I had a physicians wife tell me that chlorine (most used chem in the PW arsenal) damages the optic nerve over time. ANYWAY, the grass isn’t always greener on the other side, it just looks that way.
