Tom is on the money, I bought 2 10" camp ovens from Agri Supply to loan to groups that always ask to borrow mine. Last year someone lost two of my Lodge 12s. So now I only loan the cheap ones, if they don''t come back, no great loss. They were coated with wax and after scrubbing, it was still thick. I set the oven on 500 and left it for about an hour. Be sure to put foil in the bottom. I then seasoned them and it cleaned up well. Did get some complaints from my better half on the smell.
