I'm only interested in no-spot drying. I don't mind washing my cars the old fashioned way, but I hate having to dry them with a towel and/or microfiber cloth to avoid water spots. Not only that, but drying a car with cloths is an increased chance for scratches and swirling that I'd like to avoid. I don't care about Mr. Clean's soaps. My question is, is there any other alternative to get a spot free dry, short of installing a water softener in my house? Or, is it worth using Mr. Clean just for the spot free drying feature? I guess what I'd like to see is a hose attachment one could use for a final spot free rinse without all that expense of a Mr. Clean system.
