I have a potential contract with averitt and before I give a price i want to know the exact process to be used in 2 stepping. I have a 3700psi 4.0gpm 20h honda portable cold water. I am completely ignorant when it comes to fleet washing. from what i can understand from past post is that it involves an acid like aluma brite and then a degreeser for rinse. also as long as diluted right it can not hurt anything or material that is on a truck. I would like it if i could have the complete process that you would do with a set up like mine. I repeat I know I am charting unknown territory but i got to start somewhere. I also understand that 30 to 35 would be a good price for cleaning exterior, vaccuuming, and wiping dash and side panels plus windows. thank you for your experienced input
