If your dishwasher is just cleaning dishes, then it isn't living up to its potential. There are many things you can safely wash in a dishwasher.

Any of these listed items can go through a "normal" wash cycle, unless otherwise noted.

And, of course, use common sense when cleaning nonconventional items in the dishwasher -- if you plan to clean an item on this list, inspect it for any plastic components that might not withstand the heat of a normal wash cycle.
