What are the preferred methods for removing gum from sidewalks and tire marks from new concrete curbs at a new restaurant? I have a 3000 p.s.i. with hot water. What cleaners will work best with this unit or will just hot water and pressure do the trick? Thanks, Scott
go to home depot and get 5 gal of the purple degreaser[zep] for the tire marks
tires are carbon,oil,fiber and steel
you just need to rid of the oil and carbon
i dont use much stuff from there but they are getting better stuff
