What Cookware Will Not Scratch?

Stainless Steel

• Stainless steel cookware is highly scratch-resistant. Stainless steel may stain if you expose it to acidic foods like lemon or vinegar for a long time. Choose stainless steel cookware that has a copper or aluminum lining, as stainless steel does not conduct heat effectively on its own. To clean stainless steel cookware, wash with a mild dish soap and stiff brush. You can use abrasive steel wool to remove stubborn food particles. Do not clean stainless steel cookware in the dishwasher.

Cast Iron

• Cast iron is virtually indestructible when it is cared for properly. Although you should avoid vigorous scraping with metal utensils, you can use metal on cast iron, particularly if you use a spatula or scraper with rounded edges. Cast iron is an excellent heat conductor. Seasoned cast iron has much more nonstick capability than non-seasoned varieties. Some cast iron is enameled, which means that it has a porcelain enamel covering to make it more nonstick and easy to clean. If you use seasoned cast iron, avoid cleaning it with soap and abrasive sponges. Use hot water to remove any food particles and wipe the cast iron dry to prevent rust. Apply a thin layer of vegetable oil after use to help maintain the seasoning.

Aluminum

• Aluminum cookware is inexpensive and relatively scratch-proof. According to the Clemson Cooperative Extension, over half of the cookware available on the market is made of aluminum. Anodized aluminum cookware has a hard outer coating and is even more scratch-resistant and easy to clean. Clean anodized aluminum with warm, soapy water. You can put non-anodized aluminum in the dishwasher.

Enamel

• Although there has been past concern about cadmium levels in enamel cookware, manufacturers have stopped using it in their products, according to the Clemson Cooperative Extension. In addition to its scratch-resistant surface, enamel is easy to clean and resists sticking. As noted in "Home Comforts," enameled products are ideal for slow cooking and simmering, but they aren't the best when it comes to browning. Enameled products can sometimes be cleaned in the dishwasher, but always check manufacturer directions.
