I use the No Bucket method.

I have one of those Mr. Clean devices that attaches to your garden hose and mixes soap and water to spray on the car and also allows you to rinse off the car. Its neat because you are constantly using clean and filtered water on your car.

I also go to the local dollar store and buy a ton of cheap wash mitts that I discard after each wash. That way, there is zero risk that dirt accumulation in the mitt from previous washes will scratch your paint.
