Top product for a good price! If you want a pizza tray on which you have long joy, which is right here. At the beginning (before the first application) should the sheet rub lightly with oil and push three or four minutes at 250 degrees in the oven. Then while still hot with a dry kitchen roll towel (preferably with two pieces and baking gloves / Caution: Risk of burning!) Wipe. Is quite normal that the cloth is slightly gray / black. Then leave to cool and thin again (!), Rub with oil. One drop per plate is sufficient as a rule and can rub best with kitchen roll towel! The plate is now ready and well protected against rust.
Personally, we emphasize thin margarine before using on the inside. This allows the dough better or replace only depends not at all.
The cleaning also only happens with oil! If times but is cleaned with water: dry very well and then the drop of oil for the purpose of rust protection !!!
If that's too much work is: Stay away! All others: Enjoy :-) and last a lifetime.
