I'm not quite as particular as the above, and really haven't had any issues doing it my way. If the car's dirty I'll two bucket wash it. If it has light dust, or been rained on I'll do a Rinseless Wash.
Below is my procedure:
Put 2 1/2 gallons of warm water in a five gallon bucket with a grit guard. In this water is 2 ounces of Rinseless Wash and four plush waffle weave microfiber towels. In a second bucket is warm, clear rinse water; no grit guard.
I'll spray one panel at a time, liberally, with a mixture of 1 ounce Rinseless Wash to 15 ounces Distilled Water. I'll use just less than two mixed 16 ounce bottles on a vehicle.
Pull a towel from the wash bucket squeeze some of the water/rinseless mixture and wipe off the panel. I just wipe; no rolled towel, no z pattern, just wipe the panel. Once the panel is wiped I squeeze out the remaining wash mix and water and place it in the rinse water bucket. Again, if the car's dirty it'll get a two bucket wash.
I dry the washed panel with a Borderless Blue microfiber towel, and will use three or four for an entire vehicle. I just wipe the panel dry.
I re-pete the above procedure until all four wash microfibers are in the rinse water bucket. I'll then manipulate all four of them in the bucket together to remove any remaining wash mixture and dirt/dust. They then go back into the bucket with the wash mixture and grit guard and are again manipulated to absorb the fresh wash mixture and to remove any remaining dirt/dust.
