I just thought I'd share my dealership washing with the board. I'm in the Kansas City area. Dealerships is the base of our work throwing in a little flat work and residential. This is our 7th year. We run a two gun hot/cold machine at 8gpm (4gpm per gun). The washers thoroughly rinse the dirt OFF the car followed by 2 chamoiers per washer. The least I charge is $1.60 per car. Thats if the dealership goes twice per week. I have a $100 minimum. Running two guns and 4 chamoiers we clean on average 180 cars per hour. Dealerships love us because we are in and out. My labor is roughly $80 an hour allowing me to profit over $200 per hour.
