Seasoned with canola oil - was a mistake, help reversing

    So picked up a OK Joes Highland last week. Read that vegie oil was good for seasoning and assumed canola oil was close. Coated everything and got the smoker to like 250-275F (according to the temp gauge on the lid away from firebox) and ran it for 3 hours.

    I noticed after everything was still sticky and oil had just pooled at the bottom.

    So i did another fire burn and got it up to 325F on lid thermometer and about 400F according to thermacouple placed near opening of firebox. Ran for three hours.

    Still wet oil. A few days later I noticed it really started to stink. Then read that poeple did NOT recommend using canola oil.

    So I then cleaned the whole thing out with dish soap and water. Sprayed it down. And AGAIN ran 325F / 400F for three-fours hours.

    It smells better , but the fire box still wrecks of rancid oil. And it's STILL sticky. Man alive...

    Any suggestions of what I can do? I haven't even smoked anything yet, though I am having fun doing dry runs :)

    The last time I through in some 'campfire' wood that I had burning from a fire pit and I think it left a thin layer of brown soot on everything which was strange...

    Thanks in advance.

    Try and get the temp up to 400+ or higher.. 500 would be good.. Get it to burn off...

    Canola oil (Rapeseed) Expeller press 190-232°C 375-450°F smoke point ....fire point 660F

    Flax seed oil is a drying oil.. It hardens as it dries... Great for curing cast iron cookware...
    It has a very low smoke point.. Not good for cooking.. Takes a long time to dry to a hard polymer finish...
    Food grade is EXPENSIVE... It is refined linseed oil.... I'm of the opinion, you can use linseed oil to cure the inside of your smoker... run it on low temps until the oil hardens.. (350 ish) It hardens to a glass hard finish... Your food ain't coming in contact with it anyway....
    Or use a different vegetable oil...

    Interesting ... my new Pit Boss electric also says to cure with vegetable oil or spray. I don’t recall doing that at all with my old Bradley, just burned off a while then started using.

    Some oils have flash points as low as 230, and others 450+ ... well above the max temp an electric can achieve. Assume you’d want one with a low (achievable) flash/smoke point(?)

    Gosh I spray down the grates on my Lang with Canola oil every time I use it.
    Never had a problem with rancid smelling oil.
    I even use it on the outside of the smoker to keep rust at bay.

    Seems to be a different problem for some and not others. Really can't help here much other than I use mineral oil a lot.

  9. I used canola oil on my new smoker without any problem. That is what the manufacturer (Custom Pits & Fab) recommended... It made the grates a bit tacky, but it seasoned it well and I've had no foul smell...

    sounds like you used to much oil, if it is pooling on the bottom. I would wipe out as much as possible and then try a burn in the smoker as hot as it will go. If you still have oil inside as soon as you turn the unit off, take a rag and wipe down the inside. i use canola oil to season all of my smokers and my griddle grill but it is a very light coat.

    Thanks everyone for your feedback. I think I did use too much oil. I cleaned almost all of it out. But it all just smells bad still which is bugging me. Going to try and get more off and keep bringing it up to temp. I built the DIY expanded metal coals box which has made it incredibly easy to keep it at high temps (the lump was still warm the next morning!).

    I'm really new to this whole smoking thing (got hooked doing a 24hr sous vide brisket and finishing on my propane grill which I sealed with tin foil and put some smoldering wood chunks in to smoke it) and have been hooked. Been cooking with wood logs in my backyard in a cheap fire pit with a grate held up with bricks haha... Super excited to get some meat in the smoker!

    Hopefully a hotter burn will help clear the oil and smell. Just don't want to melt the paint.

    Get it as hot as you can (for a couple of hrs) and then spray (light) the whole interior with the water hose and close the lid.. this will in turn steam clean the inside ...

    Great idea. Will do that this weekend.

    Nothing wrong with canola. You used too much oil and didn't get it hot enough.
