About this episode

Exploring the debate around snow foam, this episode challenges the notion that foam is merely theatrical or useless in car washing. The host emphasizes the importance of 'functional foam'—foam that actively cleans by breaking down dirt and grime rather than just lubricating the surface. He discusses the benefits of foaming a dry car to maximize chemical dwell time and reduce physical effort, contrasting this with rinseless washes that require more work. The episode also touches on product formulation myths, the fun and attention-grabbing aspect of foam, and evolving car wash techniques.

Term

dwell time

""And so think about the dwell time as the cleaning time. And this goes into kind of a thesis or an idea that I have just in general of being very efficient with the products that you use...""

Dwell time means how long you leave the soap or foam on your car before rinsing it off. Leaving it on longer helps clean the dirt better.

Term

rinseless wash

""This is a major reason why I am not a huge fan of rinseless washes. Do they work? Yes, can they work? Yes, I did strictly mobile rinseless washes for five years. I've done thousands and thousands and thousands of cars in a rinseless wash method... you're not taking advantage of the technology in the liquids when you're doing a rinseless wash because you're having to touch so much,""
