The pans were beautiful. However, even though I oiled the pans, my food still stuck to them. I washed them with mild dish soap and a kitchen sponge and they got discolored. I used Barkeeper’s Friend to fix the discoloration, but it did not. Now my beautiful pans are no longer beautiful after just a few uses. I should have used parchment paper to line the pans but I wasn’t led to believe that was necessary from any of the Hestan videos I watched or manuals I read.
