When is it Time to Replace Your Cooking Pans?

A good rule of thumb is to replace your cooking pans approximately every five years. When they start to appear deformed, discolored, or scratched, it's time to stop using them and find a safe and sustainable way to dispose of them. One of the most environmentally friendly options is to recycle them in a scrap metal factory, so that the metals can be reused for other purposes. You can also hand them over to a household waste facility that will recycle them on your behalf.

Check with your local sanitation department to see what your options are, or consider sending them to TerraCycle, a recycling service that collects waste. Depending on your state, you can also donate them to a thrift store or to families in need. If you're looking for replacement frying pans, check out our guide to all available pan types.

Using a product like Bar Keeper's Friend, which is made with oxalic acid, a natural rust remover, can help bring your cookware back to life. And it's best to use heat-resistant wood or plastic cookware when cooking with ceramic, stainless steel, or non-stick cookware.
