I have been using the Mr. Clean Auto dry since it first came out a few years ago. Haven't switched to the Pro yet. I received an introductory offer in the mail for it and some deal, something like a free filter with purchase type of thing. At first it was kind of hard getting used to it, but after a while I got the hang of it. A major tip is WASH THE CAR IN THE SHADE. I used to wash it in the sun and got frustrated with the results. With trial and error I realized that the best results were in the shade. It's not completely hands free but the results are worthwhile. The first thing to do is make sure the car is cool. Rinse the car with the regular rinse on the Mr. CLean. Next, switch to the rinse with the soap. Use only the Mr. Clean auto dry soap, I tried a different one and it didn't work the same. Here's another tip, wash the car in sections. After spraying a section with the soapy rinse, turn off the spray (the switch), either brush or hand scrub the part with the soap. Rinse off what you scrubbed or brushed with the regular rinse and repeat for the rest of the car. Finally, apply the SPOT FREE spray all over the car. It feels almost as if you are painting the car lol and watch it dry. Final tips: The process is pretty fast if you have someone helping you out, pour out the unused soap back in the bottle, keep an eye on the filter, and remember, WASH IN THE SHADE. All in all I don't spend that much time washing my car and actually enjoy it.
