I've tried many car shampoos, and this one if by far my favorite. Its suds & cleans well enough. But the best part is that it has a high "lubricity"--that is, when I apply it to my mitt (the Car Pro Merino Wool mitt, in my case) the shampoo enables the mitt to slide over the paint ever-so-delicately. I hardly have to press on the body panels--which means, much less opportunity to form swirls. Then, it rinses away very cleanly. Highly recommended.
