Tractors are tractors. Wash then as you would any tractor, but the trailers are a little different. First are they aluminum and if so are they factory finish shinney aluminum. If so you DON'T want to use any aluminum brightner on them. Just soap and water. Watch your soaps! If it has caustics in it, it can also burn the aluminum and make it come out brown looking. If the trailers have already been acid washed and you are taking over the washing from someone else than you will have to continue acid washing them to make the trailers look good. You can down stream them but I find that takes a little longer than if you have a second person apply the chemical with a chemical spray system and you follow with preasure and soap. A rinse and your done. When they are hooked up doubles I generally wash straight down one side, catching the fronts and backs and then do the other side. ALSO...watch the tractors! If they have polished tanks they will have to be covered or unhooked from the trailers or the acid from the trailer washing will mess up the shiney tanks. You will then find yourself polishing tanks and thats no fun job! I used to own a custom tractor and I paid someone to polish mine. Thats to much work.
