Shouldn’t need to reseason it if you are just using dish detergent like Dawn.
I don’t really think about looking for special detergent without lye when buying (dunno why people say that dish detergent in general doesn’t contain it anymore), re-frying it once in a while makes the surface more smooth.
What do you mean by refrying?
I notice it get smother over time the more I use it.
The process where you wash it as clean as possible then apply oil and put into oven.
