I've got a nice rat tail brush I use for my wheels. It even gets behind the spokes. I always do my wheels, wheelwells and as much under the car as I can before I wash the body. I also pre-dry the car with my leaf blower. That seems to get all the water out of those cracks and crevices. Makes the final drying go much faster. I have cut my drying towel use from 3 to 1.
