We are sorry to learn about your experience. We have some important tips for you to care the aluminum cookware set. 1) Always use on low to medium heat. 2) Always cool down to room temperature before washing. 3) Avoid sudden temperature change (thermal shock) on the cookwares and lids. 4) Avoid sharp adjectives touch on the cookware surface. 5) Should burnt grease or food residue collect on the surface, it can usually be removed with warm water and a mild detergent. For extreme cases, residue can be removed with a thorough cleaning using a Soft Scrub. Do not use abrasive cleaners, steel wool or coarse scouring pads. If you are still unhappy the set can be exchanged or returned anytime as part of the Member's Mark 100% Satisfaction Guarantee.

We apologize for the inconvenience you experienced, Ange. The small holes on the iron base plate of the cookware expose the aluminum bottom of the pot to the air. As a result, the exposed aluminum can oxidize and become discolored over time, especially at high temperatures. However, we have a some helpful tip for cleaning the oxidized aluminum. Create a paste by mixing baking soda with water. Apply the paste to the oxidized aluminum surface and let it sit for a while. Then, using a damp cloth, gently wipe the surface before rinsing with clean water.

We are sorry the cookware set did not meet your expectations, Audrey. Ceramic coatings can also form a protective film through seasoning, following these steps: 1) Thoroughly clean and dry the pan to ensure no residual moisture or stains on the inner wall; 2) Turn on low heat to dry the pan, switch to very low heat, and evenly apply a thin layer of cooking oil to the inner wall (it is recommended to use heat-resistant oils such as rapeseed oil or corn oil, avoiding easily oxidizable oils like olive oil); 3) Maintain very low heat for 1-2 minutes to allow the oil to fully penetrate the coating pores, then turn off the heat and let the pan cool completely; 4) Pour off excess oil and wipe off surface floating oil with a soft cloth (no need for thorough cleaning). The non-stick performance will gradually recover during subsequent cooking.
