Are KitchenAid® beater accessories dishwasher safe?
KitchenAid brand makes stand mixer flat beaters, dough hooks, wire whisks/whips and pastry beaters in a variety of materials. Coated and stainless steel beaters are dishwasher safe and recommended for upper rack placement. Burnished beaters are made of polished aluminum and are not dishwasher safe.
Some wire whips or whisks are stainless steel with a burnished aluminum hub which is the area where the tines are inserted. These are not dishwasher safe. To clean, hand wash and dry immediately to prevent oxidation. If a burnished beater is washed in a dishwasher or soaked in the sink, it can oxidize. But, this oxidation is not harmful and can be removed.
