YEP......
Spray it down with a good oven cleaner. Then scrub it with hot soapy water (you want to strip it).
Then place it in a 200*F oven until it is bone dry.
Then coat it with a good oil (canola/olive oil---best is flaxseed oil)
All sides----use your fingers and really rub it in..then wipe it down with a paper towel.
Place it in cold oven upside down and turn the heat up to 500*F (or as high as your oven will go) and let the pan heat up with temperature rise.
When oven reaches temp.....set timer for 1 hour.
Turn off oven...leave door closed and pan inside to cool down for 2 hours.
That's the first seasoning job.......repeat at least four more times to get that smooth dark texture.
