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.
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.
Really? It sounds like you’re burning your tortillas, or your tortillas don’t have enough oil/fat in them.
Perhaps you’re cooking them too hot? Or perhaps you’re getting uneven heat (e.g. an electric coil stove)?
Corn tortillas really shouldn’t be at risk of burning like that.
