I just got this barrel, it is brand new from the looks of it. It has a solid top held on with compression ring. The inside is not painted and does not have the food liner. There is some oil on the inside From the making of it I believe. My question is can I just clean the inside out real good with a degreaser and have it good to go. They do not allow open burning of any kind. Here are some pics of the barrel. This is my first UDS build so all comments on this barrel are gratefully accepted.
