I have been using ONR at 8 ounces per gallon of water as a waterless wash and as a quick detailer and it has been working pretty well. I just spray very little when I am quick detailing, and I spray quite a bit more when I am doing a waterless wash. ONR has pretty darn good cleaning power; when using as a waterless wash I find it's best to use two towels at a time. One towel for wiping and picking up the dirt, and the other towel for drying the area.
