It doesn’t get much hotter than the EGG cookin’ in July! Make sure to keep yourself hydrated with a bit of whatever you’re using for the Beer Can Chicken. Ice Cream Sandwiches are also a great way to stay cool. Looking for some great ideas for a summer cook out? Try out a Pimento Cheeseburger or Dr. BBQ’s Spare Rib Surprise. Just don’t be surprised if your neighbors stop by for a quick bite when they smell what you’re cooking!

Last winter I left my DFMT inside my egg but never closed the bottom vent or put the ceramic top on for some reason. Alcohol may have been involved. Anyway my egg was nice and clean but it also burnt everything off my DFMT which rusted up in not time. A couple of days ago I decided to restore it using electrolytic rust removal.

Now this is way over kill for this application, the first time I tried this I was restoring an old hand plane and this method causes no damage to the good metal, it only removes the rust without damage to whatever you are restoring. Instead of baking soda I used this, pure sodium carbonate.

Here the rest of the process.

    Very cool!  It's like I'm watching Walter White maintain his egg!    =D>


    Which came first the chicken or the egg?  I egged the chicken and then I ate his leg.

    Cool!  Better living through chemistry!  I'll have to try that on some of my tools.

  • I couldn't get one of the screws out of mine this spring when I decided to clean it up so I just sprayed it with PAM and put it in my hot Egg.  Came out fine and dandy.

  • pretty cool - but how does this process compare to say, using Naval Jelly or some other rust remover? 

    FWIW, when I did my high-temp burnout, I too noticed that my now "clean" DFMT was rusty - I just took a wire brush & brushed off as much of the rust as I could, and sprayed PAM on it like probe1957 did.
    Don't get set into one form, adapt it and build your own, and let it grow, be like water. Empty your mind, be formless, shapeless — like water. Now you put water in a cup, it becomes the cup... Now water can flow or it can crash. Be water, my friend. - Bruce Lee

    Navel jelly is an acid - I think phosphoric - not toxic, it's in your coca colas.  That works too.  Mechanical removal takes some elbow grease but is how I usually remove rust.  This method is cool because it only removes the rust, and no unoxidized iron.

    Nola, thanks for the comparisons.  BTW, I remember an "old school" method that my grandad used to do on the farm in WV... he'd cut up potatoes & put them in a bucket of water, then submerge whatever rusted piece into the bucket (and, if I remember correctly, put a lid on the bucket - can't really remember, this was 25+ years ago).  Then come back in a week or 2, pull out the parts, dry them off, and they'd be good as new...

    Or at least that's what I think I recall.  I've never tried the method, and my memory of the process & the setup might be fuzzy from it being so long ago as I was just a kid at the time - but I know that the old timers had all kinds of nifty ways of doing things, and that was just one of them.  Oh what great men they were - that's why they were the "Greatest Generation" :)

    Hillbilly, good memory.  It seems potatoes are natural chelating agents.

    I wonder if it's a smiilar property that lends itself to the potato clock.

    hahahahaa... I bought an old used Shopsmith off of Craigslist awhile back & that's what I used to make my table!!  Those things are built like tanks!!  ^:)^

    That's how I knew about the Naval Jelly cuz the Shopsmith had some rust on it & I went to the hardware store & looked around & bought some of it to get rid of the rust.  Heck, I shoulda just called up Shopsmith & they prolly woulda reminded me 'bout ye olde potato method!!  :D

    BTW, I had to look up the word "chelating" and I STILL dunno what it means - let's just say that it works to remove rust!! heh ;)

    If you look at a jar of mayonnaise, it probably has EDTA ( http://en.wikipedia.org/wiki/Ethylenediaminetetraacetic_acid ).  A good example of what it does is it binds with metal ions and hangs on to them without binding to the metal.  In mayonnaise, it grabs on to the iron and other metals that give the mayo a tinny, metallic, off-taste.  They're still there, you just can't taste them.  They're also used to mitigate the effects of heavy metal poisoning.  Lots of uses...sorry, the chemist in me can't help it.  So the potatoes probably have some form of a chelating agent that helps bind the ionic iron - the non-ionic, what you want to keep, doesn't bind.
    :D

    The battery effect is a type of electrolysis.  Similar to electroplating, except in reverse - moving the iron oxide, battery-like, off the metallic iron using an electrolyte, anode and cathode.

    I can't help it!!!

    :D
    Also important to note that the binding of these ionic elements helps slow natural oxidation reactions in a processed foods (oxidation of the fat in mayo in this case).  Free ions/UV light/heat/etc. are catalysts for oxidation/reduction reactions.  Science!

    Good point, perhaps more relevant than mine!

  • Funny...just removed the screws from mine and soaked them in evaporust overnight. All rust was gone. Spread canola over everything and wiped off the excess and put everything back together.

    looks awesome.

    I have 10 gallons of evaporust in the garage for de-rusting parts from my 62 caddy. :)

    I haven't used it for any Eggin', but the golfer in me strenuously recommends getting yourself some pre-rules change Vokey Spin Milled Oil Can wedges and soaking them in Coke for an hour...  Best club in the game, hands down...

    Also a chemist...IIRC (college chemistry was long ago), EDTA's purpose as a preservative is to bind heavy metal ions needed by bacteria.  If the EDTA is holding onto all the metals, the bacteria starve or at least multiply much more slowly.

  • I'm not a chemist. I'm an elementary school.teacher. I'm going to make stuff up. The starch from the potato facilitates proper flogination of the rustification to be removed from the DFMT! This would be cool to show students though.
