This is the curb at the entrance of a store we stopped at yesterday.I will be doing a demo for them tuesday of next week.
I want to thank the other contractor who left this for making it easy for me to add another monthly account to the schedule.

the 15 degree tips can be a bit agressive for some applications and the spray pattern is so tight that it makes it easie to have lines unless you move slow

My best advice is 1- to remember that there is no one way to clean , every job is different in some way

2- use a 25 or 40 degree tip and some housewash soap (SH) and hot water (if available)

3 - or when you get done spay the cleaned area with a light solution of sodium hypochlorite this will usually get rid of the stripes too

I always use our surface cleaners to mainly wash away the dirt that the chems cleaned unless we are doing commercial properties then that is a whole different story

Also check and be sure the nozzles are free flowing and not plugged or obstructed in any way. Just something easy enough to check.
