At the beginning of every Detail, Wheels and tires are rinsed with pressurized Water to cool the surface. They are then sprayed with a high alkaline cleaner, and tires are scrubbed to remove stubborn dirt. If the Full Wheel & Tire Detail is selected by the customer, we will then spend an extended period of time on each wheel scrubbing every crevice with a variety of brushes and mitts. The wheels are rinsed and left to be further cleaned by the chemical pre-wash in the next step.
