We are sorry for your experience, Jess. To restore the non-stick performance, we recommend soaking the cookware overnight in hot, soapy water and thoroughly washing the surface the next morning. Here are some tips for you to clean the stains. 1) Soak the pan in warm water with dish soap for 1 to 2 hours. Then gently wipe the stained parts with a soft sponge or cloth. 2) Pour white vinegar to cover the stains. Heat until it simmers, then let it soak for 15 to 30 minutes. Wipe with a sponge or cloth afterward. 3) Make a paste of baking soda and water, apply it to the stains, and scrub gently with a soft brush or cloth. Rinse with water. 4) Squeeze lemon juice on the stains, wait for 10 to 15 minutes, wipe with a soft cloth, and rinse. 5) Use a cleaner for non-stick pans as instructed. Apply, wait, and wipe clean. 6) Don't use hard tools like steel wool to avoid scratching the non-stick coating, which could affect its performance and lifespan.

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.
