Polyester on Cast Iron?

bluesummers1129 Dec 10, 2013 01:33 PM

Due to some unfortunate negligence on my part, a tiny amount (just a few small drops) of polyester from a towel ended up melting onto my very hot cast iron skillet. I managed to wipe up the polyester while it was still liquid as far as I can tell, but I'm a little worried that there's still a thin spot/film left on my skillet that's invisible to the naked eye but could still be toxic. Is it still safe to use the skillet, or should I just spend another 20 bucks to buy a new one?

    So basically you burned polyester onto your cookware, right? If I am you, then I will probably try to clean it up as much as I can. You may reason the whole pan. You may just get a sandpaper and scrub the heck out of that spot. Or, you may just get a new pan like you said.

    <still a thin spot/film left on my skillet that's invisible to the naked eye but could still be toxic.>

    The polyester itself at room temperature is not toxic, but its fume is toxic. So you can make it toxic while you are cooking.

    I would just use a sandpaper or green pad and just scrub that spot clean, and then re-season that particular spot. If you think this is too much work, then you can just buy a new one for $20 like you said.

      Hmm, I will try the sandpaper idea first before I give up on the skillet. Thanks for the help!

        Don't give up and ditch the pan. It's cast iron! At most run through the ovens self cleaning cycle to burn off everything. Then reseason

          yeah don't freak over it. just try not to do it every time.

          let the cleansing fire purge and re-season.
