Thank you for your reply. It definitely works quite differently than regular car wash shampoo.
I will pick up a sponge and see how whether that releases dirt better. Even if the staining is safe, it is difficult to see whether there is dirt trapped in the wash media during the wash process.
With regular car shampoo, the wash media picks the dirt up and deposit it in the rinse bucket. With ONR, where is most of the dirt supposed to go? My rinse bucket was virtually clean, even though the mitt was badly soiled. Should the dirt flow down to the ground encapsulated in the wash solution, or rinsed out of the wash media into the rinse bucket?
I am trying to figure out how wet the panels are supposed to be during wash. Is it supposed to be... in the order of wetness, "wet" (some wash solution), "soaked" (a lot of wash solution), "saturated" (as much wash solution on the panels as possible without dripping) or "dripping wet"?
