What items are safe to wash in the dishwasher?

Check the manufacturer’s instructions. Almost all items are marked “dishwasher safe” that can be safely washed in your dishwasher. For silverware and other utensils, never mix metals. Position items in the silverware basket so stainless, silver plate, or sterling do not touch each other. Electrolytic action between silverplate and stainless steel can cause pitting in the metal (this damage is permanent).
