The Chug Wash is an automatic washer that chuggers drive into. Lori described it as a great big shower for chuggers. Chuggers like Harrison,Chatsworth and Olwin, who love being clean, enjoy it. In Wilson Gets a Wash, the trainees were having their first go in the Chug Wash, Wilson tried to avoid it and tried getting very dirty. When Koko and Brewster caught him, Wilson finally got his first Chug Wash and thought it tickles and all the trainees wanted another go.
