In this video I put the “touchless pre-wash” hype on trial: Bilt Hamber Touchless vs Koch Chemie SuperFoam. And yeah… the results don’t fit the marketing. I’m not here to admire foam for Instagram—I’m here to see what actually removes grime before you ever touch the paint. So I compared them like a normal person should: controlled dilution, consistent application, same dwell mindset, then rinse and see what’s left. I also bring out the nerd tools because vibes don’t clean cars. I’m using a pH meter to understand what we’re really spraying, plus measurement gear so the mix isn’t guesswork. The whole point is to figure out what’s doing real work on the panel versus what just looks thick in the cannon. The takeaway: “more foam” doesn’t automatically mean “more cleaning,” and “touchless” isn’t a magic word that makes dirt disappear. If you want a safer wash process, pick the pre-wash that actually loosens and removes contamination—then follow up with a proper contact wash when needed. No BS, just what works.
