We use Koch Chemie Green Star for our pre wash and Meguiar’s Hyper Wash for the contact wash. We’ve found this setup to be the most cost effective while delivering great performance. Hyper Wash>Gold Class (Hyper wash will litterally last a couple hundred cars if used correctly) To finish, we use Koch Chemie’s spray sealant/wax as a drying aid, which also works well as a small upsell for customers. Hope this helps!
@Nate Mitchell Usually around $20. It’s really quick just throw about a capful into your foam cannon, spray it on, let it sit for a couple minutes, then rinse it off and dry. It also helps speed up the drying process.
