Wet entire car.

Body first.
Wash with hot water and nice mitt.
Spray rinse.
Clay bar skim with good clay bar.
Glass gets old clay bar.
Spray rinse.

Wheels with old mitt.
Clay bar with dead old bar.
Rinse.
Every couple washes I take the wheels off...

Clean engine, interior, inside glass etc with various happy stuff. Then I do another quick hot wash and spray rinse, skipping wheels. Green people hate my water waste. Screw 'em.

Doing a quick skim with the clay bar reduces the time needed scrubbing crap off. It's cheap do it quickly and often instead of hard once or twice a year. Save the elbow grease.
