Lorenzo operates a brushless car wash. Incoming cars are put on an automatic, continuously moving conveyor belt. Cars are washed as the conveyor belt carries the cars from the start station to the finish station. After the car moves off the conveyor belt, the car is dried manually. Workers then clean and vacuum the inside of the car. Lorenzo serviced 80,000 cars in 2016.
