Here are the answers to the questions we get asked most. Now quit asking!

Where can I buy Mr. Clean AutoDry™ Carwash, Mr. Clean AutoDry Carwash Pro-Series, and respective refills?
All Mr. Clean AutoDry Carwash kits are available for purchase now in the car-care section of mass-merchandise stores and at auto-parts stores. You can find Mr. Clean AutoDry Carwash Soap and Mr. Clean AutoDry Carwash Filter refills wherever you purchased your Starter Kit, or in the car wash section of most stores.

Why wash my car in sections?
It helps you remember to rinse the soap off frequently so it doesn't dry on your car. It's especially important to do on sunny, hot days. It also helps you make sure you're washing the car thoroughly.

Why does my sponge seem dirtier than normal?
Mr. Clean AutoDry Carwash lifts dirt away from your car and pulls it into your mitt/sponge. Therefore, it is a good idea to rinse your mitt/sponge with the rinse setting in between washing different sections, and then soap up the mitt/sponge again before starting a new section.

Cleanup: Rinse out the mitt with the rinse setting when done. You might want to periodically throw your dirty mitt in the washing machine with Tide® Liquid. (Follow directions on Tide Liquid.)

What are those bead-like things dancing across my car?
These are small beads of deionized rinse water. We call them purified microbeads.

Why doesn't the water bead up after I rinse?
The sheeting action of the Dry Rinse Polymer™ works with the Mr. Clean AutoDry Carwash Filter so that a thin layer of deionized water is left on the car's surface, which will quickly evaporate, leaving a spot-free result. Next time it rains, the beads will be back—and you get to wash again!

Does it leave a film behind? Does it strip the polish or the wax?
Mr. Clean AutoDry Carwash doesn't leave behind a film, just a thin layer of the Dry Rinse Polymer molecules that are replenished each time the car gets washed. These do not strip the wax, or harm the paint or clearcoat in any way.

What is the pH of Mr. Clean AutoDry Carwash Soap? Will it hurt my hands?
Fasten your seat belts—here comes a light-speed review of high school chemistry. On a scale of 0 to 14, pH measures the hydrogen ions floating in a substance. If the pH is less than 7, the solution is acidic; if it's greater than 7, it's basic or alkaline. Pure water has a neutral pH of 7.0. Orange juice (3.0 pH), beer (4.5 pH), and unpolluted rainwater (6.2 pH) are acidic, while baking soda (8.2 pH) and household bleach (11 pH) are alkaline. In its undiluted form, Mr. Clean AutoDry Carwash Soap is slightly acidic, with a pH of ~5. But when it's diluted as directed, its pH bracket is neutral (pH 6 to 8 depending on the water used to dilute the soap). After the soap is rinsed away with tap water, the Mr. Clean AutoDry Filter comes in. It de-ionizes the water and leaves you with a spotless car.

As for your hands, we have been careful to only use one of the mildest commercially available surfactants for your skin. Also, it's important to recognize that our product is formulated near the normal pH of skin (about 5.5).

Wow, I think I see rainbows in the drying water. Are those things for real?
Yes, those are rainbows. They're caused by prism effects on the leading edge of the water as the sheet of water dries. If you still see them after your car is dry, you've spent far too long in the sun.

Why do I still see water spots on my car?
See Usage Tips. And make sure you're using the Mr. Clean AutoDry Carwash Soap and Filter everywhere on the vehicle, and that the filter hasn't turned brown (the sign that it's exhausted).

What if there's some residue left behind?
You probably missed a spot—it's either dirt or dry soap. Just hit that spot again with soap, sponge and rinse it, then finish it with the Mr. Clean AutoDry Carwash Filter spray for a spot-free finish.

Can I use this on other vehicles?
Yes. Mr. Clean AutoDry Carwash will clean lots of other vehicles. Try it on motorcycles, RVs, and boats. It also works on the windows of your home.

How many uses are in the Starter Kit Soap and Filter versus the Refill Soap and Filters?
Mr. Clean AutoDry Starter Filter provides three uses and Mr. Clean AutoDry Refill Filter provides 10 uses on average size vehicles in average conditions. Mr. Clean AutoDry Starter and Refill Soap uses will vary—dependant on factors such as how much soap you like to use, how dirty your car is, and the size of your ride.

What will happen to my old bucket and drying towels?
To be honest, the employment outlook for towels is grim. Most end up streaked with motor oil, then discarded. But buckets often find new jobs quite easily. Some will work as paint buckets or mop buckets.

What do I do with all the time I used to spend drying my car by hand?
Water sports. Here's how it works: The first few times you use Mr. Clean AutoDry Carwash, you'll spend some of your extra time watching your car dry. There's no greater satisfaction. Eventually, you'll use the time to wash another car or—better yet—your neighbors' boat. They'll loan you the boat in appreciation, and you'll be out fishing, sailing, skiing—see where this is going? Water sports.
