Wenzel ovens come with a waxy coating to prevent rust that must be burned off first. They do not have a pre-seasoning like Camp Chef or Lodge have. Place it in your oven upside down with the lid on a lower shelf and turn it on the self clean cycle. Open the windows cuz its gonna smoke a while. When the oven shuts off and cools, using leather gloves, remove it and wipe it down with Crisco all surfaces. Put the Crisco on the rag so you dont wind up with puddle saturation areas. Place it back in the oven and bake it at 450 for 1 hour. Turn off oven and let cool. While still warm you can repeat the wipe/bake procedure as many times as you wish, but I usually only do it once, then cook something greasy in it, like fried chicken or bacon, etc.
