All hypochlorite solutions shall be prepared at least 3 times each day prior to use in sanitizing the dishes used at each main meal. Water softeners, washing compounds and detergents may not be added to hypochlorite solutions. Utensils shall be racked in baskets so that all surfaces will be reached by the chemical solution while they are submerged. Other chemical-sanitizing solutions may be used only if they are approved by the department and are used in concentrations specified by the department.
DHS 190.10 Note Note: Institutions may obtain copies of the department's list of approved sanitizers by writing: Bureau of Public Health, P.O. Box 309, Madison, Wisconsin 53701.
