DOUGH HOOK CLEANING: Special care should be given to cleaning the dough hook. The Varimixer dough hook is manufactured of stainless steel and we rec- ommend that it be cleaned and sanitized in a commercial dish machine. An alternate cleaning procedure is to vigorously scrub the dough hook with a hot water and detergent solution.
