I have always heard, and followed using cooking oil. Either use oil, shortening, or lard.
Use your kitchen oven and heat the dutch oven up to about 200-250 degrees.
Once it is, use the oil and cloth to coat the oven inside and out. Put it back in the oven and get it to 300 degrees or so for a good hour. Then let it cool down, you should be set to go.
