How to Care for Knives and Cookware

Good care helps knives and cookware last longer and work better. The most important rule is to follow the manufacturer’s instructions for your specific product, since materials and coatings differ. The habits below are general guidance.

Knives

• Wash by hand and dry right away, unless the manufacturer says the knife is dishwasher safe.
• Store knives in a block, on a magnetic strip, or in a sheath so the edges do not bang against other items.
• Use a wood or plastic cutting board rather than glass, stone, or ceramic, which can dull a blade quickly.
• Keep the edge in shape with regular honing and occasional sharpening. Our guide to choosing a chef’s knife explains the difference.

Nonstick pans

• Use non-metal utensils and a soft sponge unless the manufacturer says otherwise.
• Avoid heating the pan empty or on very high heat, as many manufacturers advise.
• Let a hot pan cool before washing it, since sudden temperature changes can be hard on cookware.
• Store pans so the coating is not scratched, for example with a pan protector or cloth between stacked pans.

Cast iron

• Bare cast iron is usually dried promptly after washing, then given a very light coating of cooking oil to help prevent rust.
• Many cooks avoid soaking it or leaving it wet.
• Seasoning instructions vary, so follow the guidance that came with your pan.

Stainless steel

• Soaking a pan with warm water can help loosen stuck-on food before washing.
• Many stainless pans are dishwasher safe, but check the label for your product.

Enameled cookware

• Avoid sudden temperature changes, which can damage the enamel.
• Use wood or silicone utensils to help avoid chips and scratches.
• Check whether the pot is safe for the oven and what the lid knob can handle.

Wooden boards and utensils

Wash by hand, dry thoroughly, and avoid leaving them submerged or in the dishwasher.

When to replace

Cookware with a badly scratched or flaking coating, deep damage, or loose handles may be worth replacing. Check the manufacturer’s guidance for your product.
