A Car Wash Tunnel is a difficult environment. Keeping your Car Wash operating at an optimal level is perhaps the biggest challenge any operator faces. It requires discipline, diligence and continual investment. Creating and/or following a maintenance guide can help you stay ahead of costly repair bills and unbudgeted replacement costs. Hoffman Services offers a Preventative Maintenance Program (PM) to help you meet this challenge. You can combine Hoffman's PM service with our Chemical Program to ensure your Car Wash operates efficiently and cleans cars effectively. If you are fortunate enough to have the staff to perform your own maintenance and chemical balancing you can use the Maintenance Interval Schedule below as a guide. This schedule was developed by Tommy Car Wash Systems and can serve as a "Best Practice" for the car wash operator. It can also help you to plan and budget for equipment expenditures.
