Glad to see that you succeed in making it good again. Now it looks properly clean as i was writing about on your last post. All that black gunk is gone and it has a nice brown smooth surface.
Actually i found that cleaning it with water, a little soap and a soft brush in-between layers may help a bit in making sure that any seasoning that didn't adhere strongly gets washed off and making the surface ready for the next layer. But honestly the pan looks so good to me at this point so I'd probably just start using it like normal and as such it'll get cleaned with soap in-between the layers (if you choose to do that of course but I highly recommend) when you clean it after cooking.
