I was in town last week with an hour to kill before work and stopped at an Estate Sale at a the Howard Johnson's and found 2 iron skillets for $10 a piece. I could make out one was a Wagner and the other just looked the same. I started cruising some of the cast iron pages on Facebook and learned a lot. I was going to set up an electrolysis tank and use the battery charger but read a lot of people were using a lye bath to clean them.

They said Ace Hardware was about the only place left that sells lye other than for soap making. At Ace I found a jar that said 100% lye drain cleaner and that is good stuff. Here are 2 poor pictures of what I started with. They looked much worse in person than what the picture looks like.



I mixed 2 gallons of water with the lye and put the pans in yesterday at 1PM. My brother asked if there was room for his Vollrath skillet so we added to the bucket. Here are some pictures of what 25 hours in the lye did for them.







They are all back in the lye for more cleaning. The pan that I could not see any marking on is an unmarked Wagner. From what I read they sold their pans with the logo as premium skillets and the unmarked pans were sold at discount at place like Montgomery Wards and Sears Roebuck.

The lye will remove all the crud and then they will be scrubbed with a scratch pad. The lye only removes the crud and not rust so they will have to go in a bucket of 1 part vinegar and 1 part water to neutralize the lye and remove the light rust layer.

Then I will season them with flax seed oil. I asked on the cast iron sites about flax oil and received no responses so it must be proprietary information to SMF only.............lol.

The lye is very dangerous when it contacts your skin and eyes so glasses and rubber gloves must be worn. A few small splashes that I didn't even know about felt like a bug bite a few minutes later.

I will post some pictures as I restore these.

Hello Woodcutter.  I have never heard or thought of the lye thing.  Makes sense.  The way I know how to renew old cast iron is to build a HOT wood fire. Put the pan in the burning fire making sure there are coals beneath the pan.  The pan MUST be completely covered to avoid cracking.  After the fire burns down and is cool to the touch your cast iron pan should be completely clean.  The lye trick is a good tip.  Thanks for sharing.

I did 3 Lodge dutch ovens last fall in my gas grill at about 600 degrees. It cleaned everything off and left a light rust scale which I scrubbed off. Everything seasoned great except one spot on a lid which has a reddish spot that reappeared after seasoning. From what I read, it will probably never season again properly ever again. They advise against high heat for cleaning.

Well I'll be darned.  I have never heard of any problems with the re-season; but they could write MANY BIG books on what I don't know.  My first thought would be that the manufacturer recommends against high heat because if the pot cools too quickly it can crack.  I still like the lye tip.

After 3 days in the lye these 2 Wagner pans have all the crud removed and have been in a vinegar bath for 1/2 hour.



After the vinegar bath, they got a light going over with 0000 steel wool and washed with hot water. I put them in the oven so they got hot so I could just barely touch them with my hands. I had trouble when I did my dutch ovens with cloth rags leaving lint. While educating myself about all this restoring, I read that using a paper coffee filter is the best way to do it lint free. It works great!


Here they are with flax seed oil. I'm going to let them sit like this for a while before putting in the gas grill. (Notice the white belly from standing on my toes to take this picture)
 
 
Looks like they came back around nicely Todd!

  Now that you've done it both ways will your next cast iron be done with lye or in an electrolysis tank?
I haven't tried electrolysis yet. I think I will try that next. I want a few more old pans in the kitchen. The lye worked great without much work at all.

It looks like it did a really nice job. I was just curious. I've always done electrolysis - not on cookware but parts for old cast iron machines - & it has always worked well. I'd like to gather up some more old cookware & I think I might try out your method
