Cleaning Systems Inc. (CSI®) of De Pere, WI is celebrating its 40th anniversary in 2016. The company was founded in 1976 as a pressure washing company servicing the truck washing industry. By 1980, CSI’s focus had changed to the development and manufacture of its own detergents for use in professional car washes.

Growth necessitated expansion to larger facilities on two occasions, first in 1987 and again in 1997, when the company’s current 67,000-square-foot headquarters and manufacturing center was constructed. To commemorate the company’s 40th anniversary, the company developed a special logo, which will be used throughout the year. In addition, special anniversary-themed signage, including a timeline of key industry accomplishments, was proudly displayed at the recent Car Wash Show in Nashville, and will be displayed at other tradeshows and events throughout the year.
