Did you ever try an HP pass with your IBA presoak mixed in?
Mine does not. I use LP on two presoak passes to coat the car with presoak and leave it on the car for the time necessary. I have never seen a wash that uses HP for presoak. I have seen ones that use HP for a soap pass.Sure, my hp wash pass has presoak mixed in with it. Doesn't everybody's?
Yeah, what he said. That's what I was trying to say.When we started out with our first Southern Pride Turbo Wash back in the '80's, it did a low pressure presoak, a high pressure soap, high pressure wax and then high pressure rinse - total of 4 cycles/passes with the first lp and the remaining three hp.
Soon after we were in operation, they started setting them up differently, and we did the same - we started to run two passes lp presoak, then two passes hp. Lowered our water bill, raised our chemical bill, but cleaned better - much better.
In my opinion, hp soap is for self serve bays, where you might be heating the water and have the advantage of dwelling and or getting close with the wand to target stubborn spots and dirt either after presoak or before the foam brush.
With many operators running their hp as a cold rinse in todays IBA's, I don't think adding soap to this pass would do much, other than run up another chemical bill.
The presoak should loosen the bond of the dirt, and the hp should remove it from the surface. I don't think there is much cleaning power added with hp soap. I also agree that you would have to put massive amounts of presoak into a hp application for it to have any impact on cleaning. Probably not really practical.
