Also i use another wash mitt for the lower parts of the car.

Two sponges, 1 cloth, 1 chamois, 1 brush for wheels.
Separate tools/actions for removing dirt and for washing the body.
Three bucket fills: 1, with washing up liquid to get the dirt off. 2, 'wash & shine' type stuff. 3, clean water for constantly rinsing the chamois while drying and wiping down the car.
Two microfibre pads for polish & buff.
