Cast iron pan and Dutch oven

I had these for a few years now. Decided to give them a half ass restore or treatment or a cleaning... whatever.

Everyone told me vinegar. I figure any sort of food safe corrosive would work. Mixed it all 50/50. With water and Boiled for a bit 40 minutes.

I used this cleaning corrosive that a farmer uses to clean self feeders for his animals. Long as ya clean the surfaces good after it's OK. no way I was boiling vinegar or any other cleaning corrosive in my house So I made a fire out side.

Worked pretty fucken good. But I did use like five SOS pads scrubbed like fucken mad to get them here.

The Dutch oven turned out good too. I decided to make some stew.

Wood stove is all I got here for heat so use the stove alot to cook.

Always smells dope in here when I do.

Made some bannok and cooked in my make shift wood stove top even. Was very good.

I haven't lived here for a few winters so my cast iron stuff was very neglected.

For anyone curious I don't know what the chemical was called. But I'd recommend just using vinegar or some sort of food corrosive. Or citric acid like someone just mention in the comments.

I wonder if Orange juice would work or just boil away really fast?
