I'll have to try that next time. I've been putting CI in the oven and running a cleaning cycle. That works but really stinks up the house. I've heard that oven cleaner and stick in plastic bag for a couple days softens the old seasoning but have not tried it myself.
If you do choose to burn it out, I can't imagine that you could get enough heat using charcoal to do any damage. Just DON'T splash water on it or otherwise cool quickly and you should be good to go.
Here's a pretty good blog about seasoning CI
(except I don't agree with her concern with damaging CI in the cleaning cycle. Anything hot enough to damage CI would melt the oven walls themselves!
