I have a Lodge Logic Dutch oven that I took camping last summer and lazily left outside for almost an entire year.
Were preparing for this summers camping trip, and I go and grab it, and this is what I find:
So I'm like 'Dammit Jim!' This thing was covered in rust, inside and out.
So I decided I needed to clean it up, and this is how I did it.
I took a crab pot big enough to hold the dutch oven. I put the oven in the pot without the lid on. I poured in one jug of white vinegar. I then added enough water to cover the pot by a couple inches. I then put the lid on the oven, and poured enough water more, to cover the entire lid.
I let the oven soak for 2 days.
After two days, I pulled the oven out, and wiped it dry with a rag.
Be sure to use a rag here you can toss, as it's going to get rust ALL OVER IT. This is kinda messy.
After the pot is dry, I then took a drill with these two attachments:
I then proceeded to clean the shit out of the oven. I found the second brush worked best, although the first did come in handy at times.
It wasn't terribly hard at all, and took maybe 1 1/2 hours.
Heres the final result:
As you can see, it cleaned up rather nice.
Next I washed it with hot soapy water.
Dry it COMPLETELY.
Now to season it.
Rub it down in grease or oil, whichever you normally use, I used vegetable oil.
I baked it face down on a cookie sheet on 250 degrees for 4 hours.
This obviously either wasnt hot enough, or long enough, as the pot was really sticky to the touch when I took it out and cooled it down.
So I heated the oven back up to 350 and baked it another 45 minutes.
Checked it out after it cooled, and its perfect.
