I agree with everything he says. The only part I would recommend a change is the rinse method. It is better to use just the flow out of the hose (IE not a spray attachment) to rinse your car. The reason being it the water will just roll off the car in a sheet and there is less water to wipe off in the end.
Helps with keeping water spots off. Especially if you can't quite properly time washing your car in the evening.
