I've tried Adam's Detail Spray before, and thought it gave a good shine. However,
Optimum Instant Detailer is cheaper (if you buy the concentrate) and works just as well. It even has the same cherry smell, which makes me wonder about rebranding to be honest.
I've never used a waterless wash on the whole car, although my favorite for spot cleaning is
Poorboys Spray & Wipe. I admit that I haven't tried many, because there's no reason to buy something else if S&W works well for me, which it does. I have an unopened bottle of Optimum No Rinse, because it gets excellent recommendations, but it isn't waterless.
