Skepticism is understandable since these "Rinseless" products are relatively new to the world of detailing, so I can definitely understand where some of you are coming from. I was in the same boat...until we released our new juice last year.
Just know that all of these products have limitations. They are made to speed along the cleaning process of a light to moderately dirty vehicle, while still minimizing the risk of inducing swirls/scratches into your paint.
If you've been in the woods for a weekend and your truck is HAMMERED dirty, then yes, a power washer is your friend. If you drove it to work for a few days and it's dusty, or you got caught in a day or two of rain, then a Rinseless Wash is your friend. It cuts the time it takes to clean the truck in half, less mess, less tools, and it's just as safe as a two-bucket wash...when performed correctly.
