Wearing gloves and eye protection through all my encounters with the Lye water. The Lye will eat up most of the carbon and get you back to the metal. Then you can reseason and use like they were new.
You can use the Lye solution several times. Just make sure you add the Lye to water and not water to Lye.
You can pm me if you want. I have a stubborn skillet in lye water for over a month now....
+1 on the order of addition there...nice basic chemistry lab safety to keep to.
have you tried electrolysis on the stubborn skillet? you can look here for some info:
