Yes. A good rule of thumb is to leave out wood, iron, aluminum, crystal and any china not labeled dishwasher-safe. Hand washing is a great choice for those items, as they can be permanently discolored or damaged in the dishwasher. Follow the manufacturer’s recommendation on what is dishwasher-safe. Silver can be placed in the dishwasher but do not mix silver and steel in the same basket compartment as this can lead to tarnishing. When washing China, ensure to leave enough gaps between items.
