Just trust it. Let it do what it says it'll do.
If it's a nice day, I just leave my car in the drive to dry. Sometimes, I've just moved into the garage and let it dry there. But you can also just drive away with the car wet. It will dry just the same with no spots. Believe me, I've done it.
In regard to the process: Get out of the old carwash zen thing. This is a revolution in car care. It's better for your car. First, everything you need to completely wash your car is literally in the palm of your hand. Don't go for a bucket or drying towels. Just fill the soap reservoir in the AutoDry sprayer with the AutoDry soap and hook up the sprayer to your hose. Grab a sponge or carwash mitt. Turn on the water full blast.
1-Rinse your car with the plain rinse setting. It loosens the dirt and cools the surfaces. Turn off sprayer.
2-Switch to soap setting. Turn on sprayer. Spray soap directly on the car and onto the mitt. Wash in sections, top down, being carefull not to miss areas. Use firm strokes when washing. The soap will not suds like dish soap. It's low-sudsing, but it cleans like nothing you've ever seen. It is formulated specifically for the kind of dirt that collects on cars. It's not something for dishes or laundry that is adapted for cars. AutoDry soap is formulated to remove road dirt from car surfaces. That's it. And, yes, Procter & Gamble spent four years researching road dirt and car surfaces. (TIP: I always wash my wheels and wheel wells first with a sponge or brush because they are always more filthy than the rest of the car and I don't want to contaminate my carwash mitt that I use on the rest of the car.) As I wash in sections, I occasionally rinse with the plain water setting so the soap doesn't dry on the car (however, the soap is more forgiving in this regard than other soaps.) Try keeping the car wet until you're completely finished washing. Then, rinse all suds off the car with the plain water setting. Turn sprayer off.
3--Switch to AutoDry setting. Turn sprayer on. You'll see the water come out of the sprayer in a very fine, fan-shaped mist. When the spray hits the car, you'll see what looks like millions of tiny ballbearings dancing over the car. These are fine air bubbles. Again, top to bottom, rinse the car, saturating it and keeping the sprayer about a foot away. (TIP: Concentrate on side mirrors, gas caps, gaps that collect water and will drip later. If you do that, even those drips will dry without spotting.) Remember the wheels and wheel wells.
4--That's it. Really. Go put the hose away. Put the sprayer away. If there's soap left in the reservoir, leave it for next time. Leave the filter inside. The water on the car will evaporate. There won't be spots on anything. Go watch a basketball game or go run an errand. Doesn't matter. Actual drying time depends on air temp, humidity, sunlight etc.
If you notice, after the car dries, that there is dirt in a patch or two, just go back and hit it again with AutoDry soap and AutoDry spray. This was your doing. You missed the spot unknowingly or you lifted up as you went over the area. Be thankful. Because you've done this many times in the past and didn't know it because you didn't let the car dry. What you did was immediately dried the car, grinding that dirty residue into your paint. That's where the swirl marks come from.
You can even wash your door sills with AutoDry. I soap up my mitt and wash the sills with it, not spraying them directly. Then, rather than rinsing with plain water, I go directly to the AutoDry rinse because the spray pattern is so precise and easy to control. I spray directly onto the sills while holding a piece of plastic or cardboard behind what I'm spraying so the water doesn't get into the car.
I know this is different than what you're used to, but you'll get used to it and eventually you won't want to wash your car any other way. In the winter here, I can't use AutoDry for obvious reasons, and I just hate having to take my car to a carwash.
Let me know if you have any questions.
