Well, when I ordered a gallon of Optimum Car Wax, I took the opportunity to buy a few bottles of the Car Wash as they were going for $7.99 for a 32 oz bottle - not a bad price when compared to some other premium washes.
The car wash has a very pleasant scent about it, very much like their car wax. The instructions on the label state to use 1 oz for every gallon of water. The product generates a lot of suds (if that's your thing) and does have high lubricity. The product cleans well, does not appear to strip wax/sealant and rinses cleanly off. Then again, you can probably say this about a host of other good quality car wash products. I really don't know what else to say about the Optimum Car Wash - it's not a bad product, nor will it "rock your world." Personally, I do like it and since I have a few bottles of the stuff, I'll continue to use it. It's a simple, honest product that gets the job done.
