The mixture sticks no matter how much oil I use. Also, I was careful from the beginning not to damage it, but even the soft side of the sponge scratches it. In 3 uses, the coating had already come off in several places, which rust immediately if they remain wet (even in the dishwasher). You get what you pay for. It's better to buy the disposable aluminum molds that supermarkets have, or spend a little more and get Pyrex or another brand that can be washed in the dishwasher.
