Hi There,
Here is the before and after spending 6 days in the e-tank, then 5 rounds of seasoning with Crisco heated up to 200*, then 300* and them 500* for and hour.
I had never left a piece of cast iron in the e-tank for more than a couple of days, so I wasn't sure what to expect. I was pleasantly surprised how clean it came out, I would guess that probably 98% of the rust was gone and the wire brush took off the rest very easily. I didn't expect that the inside of the bowl would come out so clean!!
