I didn't write this, but a friend of mine did, and this is how I also wash my truck when I'm in a rush. The Lazy-Man's Detailing thread inspired me to put it here for you all to see.
First, I'll tell you how to wash and wax your car in an hour or less. This does not include any polishing so this method won't correct any defects. However, if your car is in good condition already or you just want it clean and protected, this method is excellent.
Products you will need:
2 gallon capacity bucket
1 wash pad, I like to use chenille covered foam pads
4-5 16" x 16" microfiber towels
2-3 terry cloth or cotton towels

1. Using a capful or approximately one half ounce of Optimum No Rinse (ONR), add it to one gallon of water in the bucket.
2. Clean your wheels, tires and fenderwells using the ONR mixture and your brushes, wipe dry with the terry cloth towels.
3. Dress the wheels and fenderwells with your tire dressing-and don't forget the fenderwells! Dirty fenderwells detract from an otherwise clean and shiny car!
The reason to do the wheels and fenderwells first is so when you apply the tire dressing, any overspray will be washed off the car during the washing step.
4. Empty out your bucket and refill with clean water, adding one half to one full ounce of ONR (less if relatively clean, more if really dirty).
5. Using a chenille covered foam pad or a wash mitt, wash one section of the car at a time and dry immediately using two microfiber towels, one for the first drying pass and making sure you leave a little moisture behind, use the other towel for a second drying pass. If you get the panel completely dry with the first towel, then don't go over it with the second towel because rubbing even a soft microfiber towel on dry paint can leave streaks.
Once you get the process down (it may take a couple washes to really nail it) you should be able to wash the body of your car in 20 minutes or less unless it is really filthy.
6. After washing open your doors, gas cap door and trunk or hatch and wipe down all the jambs.
7. Using Optimum Car Wax (OCW), spray onto a section at a time. Don't soak the panel, just a mist should do. Spread the wax over the panel, flip the towel and wipe to a haze free shine. If you can use a detail spray, you can use OCW, it is that easy. Depending on your area, wash habits, etc, you can expect 3-5 months durability. Honestly though, it is so easy to use you will probably use it every few washes. Shouldn't take more than 10 minutes to do the whole car. In fact, you can also apply it as you dry each section when washing with ONR to save even more time, or apply while washing and apply a second coat for even better protection with very little additional time spent.
8. Clean your glass inside and out.
Stand back and admire your shiny car!
