An aluminum Dutch oven may be washed with your other dishes in hot, soapy water, or even cleaned in
the dishwasher.

To clean your cast iron Dutch oven after producing a delicious meal, first scrape out the remaining food with a plastic scraper as soon as possible. Never store food in a cast iron oven. Then fill with 1 or 2 quarts of hot water and scrub with a plastic (non-abrasive) scrubber or vegetable brush. Some cooks never use soap in their cast iron ovens, others use just a few drops of soap, being careful to rinse well. Whichever method you choose, dry the oven completely immediately after washing, and coat with a very thin film of vegetable oil. Replace the lid and store in a dry place.
