Is there a particular chemical that I need to be adding to my detergent to remove road film . I 2 stepped yesterday and had to brush after applying detergent ( I also added some NaOH to the detergent to beef it up). On this job I used 20% H3PO4 thru a shurflow as client didn't want HF on site I also used hot water at 100 degrees Celsius, up to 3000psi with flow of 4 GPM. Any help would be appreciated. As I can't get the brands of detergent you guys use over there.

Jason
