A hot word today is green (and we were 'green' before it was assigned it a color!), so here is what we are doing to be green...
Although we use several different suppliers for our cleaning solutions and car wax products, each product that we select is bio-degradable. In addition, our waste water goes into the sanitary sewer, so there is no leaching of soaps into the ground as you will find with all home driveway washing.
With an electric eye, our sophisticated computer system measures the car as it enters the car wash, and passes that information on to the rest of the equipment in the tunnel. Consequently, the water and cleaning solutions only turn on when the car is directly beneath each piece of equipment.
Our nozzles that spray the water on the vehicles are designed to focus the water into a specific spot, which increases the pressure, but reduces the volume. This allows us to maximize the effectiveness of the water.
