An apparatus for cleaning an article includes a drive belt and a wiper belt. The drive belt defines a first article engaging surface substantially parallel to a second article engaging surface of the apparatus and positioned to receive the article between the first and second article engaging surfaces. The drive belt is powered to move in a first direction such that the first article engaging surface imparts a forward motive force on a side wall of the article. The wiper belt defines an article wiping surface positioned to contact the article, the wiper belt being powered to move in a second direction opposite the first direction such that the first article wiping surface imparts a rearward wiping force on the article. |
