I have an enameled carbon steel pan that I use almost daily. Even though I use oil when I cook sometimes a bit of what I cooked remains in the pan. Instead of madly scrubbing at it with a scrubby pad I just pour some ordinary salt in the pan and scrub it around with a folded paper towel and it's spotless again. A quick wipe with a soapy sponge then rinse and it ready to go again. Does anyone else use this method on their pans?
