Things You Thought Could Go in the Dishwasher But Really Shouldn't
Crystal glasses are especially vulnerable. Food particles can etch them; heat can cause cracks. After hand washing (it’s usually safer than using the china/crystal setting), dry with a cloth that hasn’t been laundered with fabric softener, which can leave a film.
Wooden spoons can warp and crack. If you don’t mind replacing them frequently, throw them in; otherwise wash them in the sink.
Brass items should never see the inside of a dishwasher. Hot water can remove the natural protective layer that forms on brass.
