  • Biggest Abrasion for the Buck

    It took about 20 pizzas, but the coating on my lasagna pan:

    https://www.amazon.com/Wilton-Nonsti...dp/B004EBLXT8/

    eventually gave up the ghost. It's a pretty heavy duty pan, and I didn't want to throw it out, so I took a shot at removing the teflon coating.

    After about 4 hours total labor trying to abrade the coating, I was able to get it down to the bare metal, but I'm considering doing this with another pan, and I'm hoping someone can suggest a better way.

    I basically went with this

    https://www.amazon.com/Makita-HP1640.../dp/B002QB1ADW

    plus this:

    https://www.amazon.com/3M-Paint-Rust...dp/B000BQT4UK/

    The brush is a little flattened now, but it survived the journey surprising well. With it's diameter, though, I couldn't do the corners. The brush was probably 45 minutes of labor, but the corners were a brutal 3 hours of scraping with 40 grit sandpaper.

    I made a larger version of this

    using a nut and bolt, and while it polished the pan really nicely, the green scrubbers I had on hand didn't take anything off.

    The pan was $8, so I'd like to come in considerably south of that for the materials to remove the coating- maybe $4 or less.

    These might work for a DIY buffer:

    But they're out of my price range.

    I'm reasonably certain that I can get away with a 2" diameter on the corners so this might work

    but I'm not sure. I like the 80 grit aspect, but I'm concerned about longevity.

    I like the price on these:

    and, being used for nail polish, I think they're up to the task, but I really have no idea.

    I'm open to absolutely any approach that can sand teflon off steel while costing close to nothing.

    heat, do you have a self cleaning oven? put it in there and do a clean cycle. at least thats how I ruined a teflon coated pan.

      That is not too wise as Teflon out gasses a dangerous product when "essentially" burnt up.

        Did your cleaning cycle remove the teflon? I could definitely see it ruining it, but not removing it necessarily. Even if it did take the teflon all off my bigger concern would be that I've heard stories of burned off teflon going airborne and depositing a white dust on the surface of the oven.

        Plus the safety factor that Lew mentions- although I'd be doing it in a BBQ. I just don't want to coat the interior of the BBQ in a white powder.

          Sand blasting it? Use soda if you don't want to hurt the metal.

            I probably should have put this at the top of my post, but my budget is 4 bucks.

              For this particular job? Maybe you can justify it for other projects.
              Well, guess you could heat up the pan with a propane torch and be careful to not breath in the fumes. Maybe pool acid?

                That is fact. I had an African Grey and I made sure to watch any fumes. Seemingly the most inteligent pet or animal freind. Birds have a funky structure.

                  I don't get this mentality. $4.00 Take it by a sandblasting company and ask them. They will probably do it for nothing the next time they fire up the sandblaster. Simple.

                      Bad move. Both the dust and the fumes are very toxic. Grinding the teflon produces heat and vapors. It is called teflon fever.

                      The pfas/pfos compounds used to produce teflon contaminate drinking water at levels even in the low parts per Trillion - with a T. Reports suggest 3M has covered up the toxicity for years.

                      Old scotchguard is especially bad. But PFAS is in a lot of other products and regulation is lacking.

                      It isn't something to mess with. Get some cast iron.

                          Why spend the time, endanger your health, and spend even 4 bucks worth of abrasives on an 8 buck pan that will be next to useless without its Teflon coating? Anything you put into it will stick and burn.

                          Do as Glug says and get good cast iron. Expensive, sure, but cheapest and best in the long run if you keep it seasoned properly.

                            I didn't do it on purpose. but yah it does stink, I just thought it was the spillage in the oven. I rescind my idea of using heat. and I have a suggestion from a lady friend, go to target or walmart and buy another pan for four dollars.

                              Is this thread for real? Seems to be a bit far away from April fool's.
