Yes.
Apparently you can’t hear up tortillas in them without it forever getting scorch marks. I suppose only thing I haven’t tried is using a machine sander on it to try to remove it.
Really? It sounds like you’re burning your tortillas, or your tortillas don’t have enough oil/fat in them.
Are those scorch marks an issue beyond aesthetics though? (Genuinely curious, not judging)
In that case, try boiling a mixture of baking soda and water in it, then scouring it using tongs with copper wool (I’d probably use steel wool, but that might also leave scratches, I don’t know). If it’s giving your food a taste, it is coming off, just really gradually and under high heat.
Barkeepers friend (powdered metal and glass polish/cleaner, typically comes in a cannister) will get that off with a little bit of elbow grease.
Half the pans I’ve bought i got at a thrift store for like a buck because people thought they ruined them with a little bit of scorching., and I’ve gotten some nice stuff.
Unfortunately haven’t found that cheaply available in Finland. I know about it too. It’s the only thing I haven’t tried other than straight up sanding it
So the legend of bar keepers friend is that it was invented after someone boiled a bunch of rhubarb greens and noticed it cleaned the pan. I reckon any green high in oxalic acid (the main ingredient in BKF) should do similarly enough to the actual product to let you know if it might work.
