There have been a lot of posts lately about the best presoaks for touchless washing. What is the cost per car for those of you that are happy with their chemicals?
I can't remember the exact number but I'm thinking we are around $ .80/car and have pretty good results. We are using a dual eductor hydrominder with JBS Action presoak high AT-102 and Action high PH booster AT-150. Purple hydrominder tips on both and bump it up to an aqua tip in the springtime on the presoak only.
