Contrary to the assumption in the question, the Aslett Clean World Foundation is not located in Pocatello, Idaho. The nonprofit organization is actually based in Los Angeles, California.
Founded by cleaning expert Don Aslett, the foundation promotes cleanliness, organization, and environmental stewardship. It operates the Museum of Clean in Pocatello, Idaho—a separate facility that showcases the history of cleaning tools and practices. This museum may be the source of the confusion.
If you're looking for the foundation's headquarters, it's in Los Angeles. If you want to visit the Museum of Clean, head to Pocatello.
