I have used cast iron and steel pans fro a few years and season them in the same way. 1st make sure that you get all the oil that has been applied for transit purposes. I had some small thick steel 'Balti' dishes that had a thick layer of oil/grease on them. I put the dishes (not the wood holders
) in the dishwasher and they came out pristine. I then put them on the stove on a medium heat, add a small amount of oil and coat the inside with the oil. I then left it on the low to moderate heat for around twenty mins (don't leave unattended!). After that, every time I had the oven on I placed the dishes , wiped round with oil, in the oven. I even used them to make Yorkshire puddings in (big ones!). I also did this with my Wok/Karahi. As a previous mail stated NEVER use detergent to clean your pan. I use a stiff brush and very hot water. If food is burnt on, just let it soak, it will not harm the pan. A bit of rust in the bottom won't hurt either as long as you oil the pan when it is dry. Just coat with any oil applying with a bit of kitchen towel/role.
At the end of the day, use the pan/wok as much as possible. There is no substitute for a lot of use. Just be patient. It takes time to build up the patina (coating).
