Why did my Zwilling Aluminium pan cookware surface corrode just after 1 month?
On March 3 2021, I bought this Zwilling 33 cm / 13 inch Aluminium deep saute pan with lid. Please review pictures below, inside my red circle. The coating on the surface appears to have corroded! Why? What went wrong?
I was careful not to scratch or corrode the coating! I used sponges to clean. I used plastic heat resistant Turners. I never stacked anything inside this pan.
I used this JUST on Electric Cook Top in my house. I never knew overheating can damage non-stick surface! Someone asked how do I heat it? I usually oil the surface with Sunflower or Safflower Oil — because they have high smoke points! I usually just use medium or medium high heat. SOMETIMES I crank up the cooktop to max heat — if the pan holds many ingredients and the food is cooking too slowly — or if I want to stir fry rice, noodles, vegetables, seafood like Asians.
At max or high heat, I NEVER leave the pan empty or dry on high heat!!! On low to medium heat, the pan can be empty or dry when I am offloading ingredients and onloading new ingredients. Like if I finish stir frying ginger and rice at high heat, I turn down cooktop to low heat. Then I pour out vegetables. Now pan is empty. Then I pour in my raw vegetables and crank back up to high heat.
