i posted a message a few days ago about cleaning concrete and it was giving off alot of white powder, some people suggested that i may be taking a layer off the top. the tips that are on it are 25025's i have a 3500 psi machine 4.5 gpm, should i try to put 25030 on there that will drop the pressure to about 2500 psi i think?? thanks for the help.
