To clean a Dutch oven, soak it in warm, soapy water and scrub it gently with a soft sponge or brush. Avoid using harsh chemicals or abrasive materials that can scratch the surface. Always dry the Dutch oven thoroughly before storing it. When cooking with a Dutch oven, use wooden or silicone utensils to avoid scratching the surface. And always store it in a cool, dry place, and avoid stacking it with other heavy pots and pans.
