A nice shampoo for your wash regiment.
A highly concentrated car wash shampoo, gentle but effective. A good shampoo not only suds up nicely, but it also needs to be slick. Slickness is actually a more important feature when picking a car shampoo than suds, as any “rinseless/waterless washes” only rely on slickness and not suds. Biodegradable and pH neutral.
Dilute 1:500 ~ 1:700.
