There are 3 stages to a comprehensive exterior wash.

Stage 1:

Pre-rinse/Contact wash. The vehicle is foamed to encapsulate and emulsify contaminats and is then rinsed to prep for the contact wash that will remove most surface level contaminants.

Stage 2:

Chemical Decontaminaion. This stage intorduces Chemicals to further breakdown deeper levels of contamiantion that the contact wash couldnt remove. The vehicle is then rinse again to remove and dilute residual chemicals on the surface.

Stage 3: 

Clay Decontamination. This stage introduces the final cleaning stage and preps for a Paint Correction Service. A piece of Synthetic automotive grade clay is used to pull and lift up contaminants called industrial fallout which can be iron particals, tar, sap and other mineral deposits.

All of these stages except the clay stage are done to the wheels as well.

Tier 3:

Steaming:  This is the highest level of cleaning power which will disinfect and breakdown any contaminats through a combination of heat and water this meathod is powerful and effictive while still being gentle on all surfaces.
