In the very early days of washing cars, the industry was generally not overly concerned with how much water or electricity carwashes used. To be fair, washing cars before 1946 consisted mainly of a gallon bucket, soap, and a sponge. These small scale wash stations may have used a total of a few hundred gallons of water throughout an entire day… if the whole town needed a cleaning.

 As populations and technology has grown over the last few decades, the industry has steadily increased the number of resources used to wash cars, especially water. According to “Education in Nonpoint Source Pollution Prevention,” a study published by, an average driveway wash uses 116 gallons of water. In fact, the report says, “Most commercial carwashes use 60 percent less water in the entire washing process than a simple home wash uses just to rinse off the car.” They further state, the average commercial carwash uses around 46.4 gallons per vehicle. 

Needless to say, using more than 45 gallons of water to wash a single car poses a significant environmental issue. With an estimated 8 million cars being washed daily at wash facilities, our global water usage of ~ 360 million gallons of water per day to wash cars is ridiculous.

This statistic alone inspired my own carwash transformation.
