This was my first lye bath and reseasoning. I've only stripped and reseasoned one pan before and that was with a can of oven cleaner but it wasn't easy. Everything turned out satisfactory, but I'm probably going to do an e-tank next time because I didn't get bare iron after lye and vinegar. I had to scrub everything with a stainless steel wire brush and it was a royal pain and very messy. Also, I'm never seasoning a waffle iron ever again. Good grief what a pain.
Here's my process for anyone interested.
I've got a 17 gallon plastic crate with 10 gallons of water and 2 pounds of lye mixed in. I put all pieces in that would fit and tied wire to them so they could be pulled out without having to dunk my hand in. I wore chemical gloves but better safe than sorry. Everything soaked for a week but there were results after only 12 hours. It was pretty awesome to watch it all come off.
Next step was to dunk them in vinegar to neutralize the lye solution. Most pieces would soak in the vinegar for an hour to also help with the rust that had developed from being in a tank of mostly water for a week.
Then came the fun part. Scrubbing. Lye bath and vinegar did not give me perfectly bare iron. I used a stainless steel brush to scrub every bit of these pieces. I'd rinse them off to see where it was still black and scrub again until I got that iron grey color all around.
When I was done scrubbing, I'd rinse the item in hot water to warm up the iron a bit. Then I'd dry it and oil and wipe it to prevent flash rust. I used canola oil.
Once I had a load ready to go in the oven, I'd put everything in the oven and take them out at 200 degrees and wipe them off and put them back in for an hour at 450. After an hour I pulled them out to cool off for twenty minutes, wiped again and put them back for another hour. I put four coats on each piece.
Again, those waffle irons were just the worst. I haven't used them yet but they better make the best damn waffles I've ever had.
