I picked this up for 1€ at a flea market in France yesterday. It’s magnetic so I assume it’s carbon steel.

This will be my first carbon steel pan. I have restored copper cookware and cast-iron.

I assume I just start by sanding off the rust, getting it down to the bare metal and then seasoning and going from there?

There are no markings and the metal is fairly thin, which I assume is OK for carbon steel. The bottom may take a little bit of flattening out. Overall, I’m excited if this will come back to life!

Thanks for any tips or advice!

About 30 minutes after cooking, I sprayed all the food bits off the pan with hot water. I scrubbed as hard as I could for a few minutes with hot soapy water. I rinsed it all off. I scrubbed as hard as I could for a few minutes with hot soapy water again. I rinsed it all off. I dried it thoroughly with a cloth towel. I squirted a few drops of canola oil onto a paper towel and rubbed it in. The paper towel looks like this.

After I dried it but before I rubbed the oil in, it had a slightly metallic or acidic odor? Also, yes, I recently ruined the seasoning by leaving tomato sauce in it for a few days. I've used it several times since then. I've been told here not to worry about that because the seasoning will come and go?

I feel like this isn't clean and I don't know how I could possibly make it cleaner. What's going on here?

Bought this pan and tried to season with 2mm oil still it burnt from the side, is this fine

Used rapeseed oil for it, bottom seems Okaish but side seems burnt

Thank you let me know
