i just used the Mr Clean Auto Dry system today. it really works fabulously! and i live in texas, which i think has the hardest water in the united states.
however, today, i did not follow the Auto Dry's instructions. instead of soaping the car with the Auto Dry mechanism, i just used a bucket full of the Mr Clean Auto Dry soap and a cotton mitt. i wet the car normally, scrubbed really good with the mitt, then rinsed the soap off using the auto dry setting. uses a lot less soap, and i found it be a lot faster. car dried off with only a couple water spots (from where i missed some spots), and i used a waffle microfiber towel to pick up the few water drops that were left. there was so little water left on the entire car that i could've dried it off with half a paper towel sheet.
