We are sorry for your experience with this pan set, Sam. Here are some tips for you to maintain the superior nonstick performance and bright colors. Always cook on LOW TO MEDIUM HEAT. HAND WASHING RECOMMENDED though these are DISHWASHER SAFE. Always cool the pans down to room temperature before hand washing. The use of high heat and a sudden temperature change can cause metal fatigue, warping, deformation, non-stick deterioration, chipping, discoloration. However, a deep cleaning of the non-stick surface can help restore performance. This may include soaking overnight in hot, soapy water and then thoroughly washing the surface the next morning.

Thank you for following the instructions, Janice, as it is very important. To restore the non-stick performance, we recommend soaking the cookware overnight in hot, soapy water and thoroughly washing the surface the next morning. Besides, as you can see on the bottom, the small holes on the iron base plate expose the aluminum bottom of the piece to the air. The exposed aluminum oxidizes in the air at high temperatures due to its nature. Therefore, after repeated use, the aluminum at the bottom will discolor. However, we have a tip for you to clean. Baking soda: Mix a suitable amount of baking soda with water to form a paste. Apply the paste to the oxidized aluminum surface, let it sit for a while. Then gently wipe with a damp cloth, and finally rinse with clean water. If you are still unhappy with the set please know you can exchange or return it anytime as part of the Member’s Mark 100% Satisfaction Guarantee.
