I've never had this happen, not that it wouldn't, I've just never had it happen. I also don't use the grill, I use my oven so maybe I'm not getting everything off. I also think the lemon and salt get rid of some of the char flavor (that could all be in my mind though
). After scrubbing I do wash it and dry in a warm oven before I coat it with crisco.
