the only time i'd use steel wool on a cast iron pan would be if i were taking the seasoning off it. otherwise i use a plastic scrubby and hot water if there are chunks on there that i want off. i may use just a drop of dish detergent on a cast iron pan if i've been cooking meat in it because i'm sensitive to meat fat smells and that is one way of getting the fat smell off there.
then i will heat it up to dry it and wipe a very tiny amount of vegetable oil on it and put it back on the shelf until next time.
when i make something with butter fat or vegetable fats of any kind i just use hot water plain and the scrubby if needed but i don't need detergent then. if there aren't any cooked on stuffs on the pan i'll just wipe it out and leave the vegetable fat on there from before and then i don't even need to wash it at all or get it wet. i do wipe out any extra oils because i don't want to attact any bugs or critters. it is stored with a good lid on it so no bugs can get in easily anyways, but no need to tempt anything by making it too easy.
i've not had to reseason my current cast iron pan since i got it. just using it works fine for adding more seasoning to it. i did wipe on some more oil and baked it for the outside when i got it but that was it. it isn't a perfect season job now, but i don't care. there's some flaked off the sides which don't get used for anything anyways so no biggie to me. it cooks fine, nothing sticks, makes pancakes and sausage just how i want it to. so i just leave it alone and use it. i do want another pan for when we make pancakes and sausage because i only have one pan now and i'd like to not have to switch between items. it's on my wishlist to get a nice flat for pancakes. i sure don't need the rim of the pan and it gets in the way for flipping pancakes.
