Royal and Proteam for my van as well.
So how do you tackle the filthy jobs Matt?
Just like any other good rug sucker, for trashed rentals and commercial, I pull out the Royal to prevac, then pre spray with either a butyl based liquid pre spray, or my powder Grease Eraser from Chemeisters, and HWE with my
Boxxer XL at 500psi. I'm a hack, so I get too lazy to put a blower down. I just do more dry passes than normal for my dry times to be awesome.
On the houses for the pretty people, I use my Proteam, the grease eraser cut in half with a little oxygen for light colored carpets, rinse at 500psi, collect a check and make out with the soccer moms, and take off to my next job, lol.
I've got a crap load of extra pre spray in my shed that I need to use up,
chemspec enzyme, other liquid pre sprays, etc, so my chemical cost this year should be a lot lower than last year.
