enamel bread tins - bread sticks

[PinkSwimGoggles]

bread has starting to stick.
I use them only for bread, nothing corrisive.
use butter.
wash them by hand with a soft cloth after soaking with washing up liquid.
what can I do to make them less sticky again?
they were bloody expensive so rather not replace them

Try buttering them and then flouring. Maybe put some baking parchment in the bottom.

thanks I will try that

tbh it sticks more to the sides than the bottom

Flouring should help and maybe try vegetable oil instead of butter (higher smoking point so less likely to burn). Are the tins completely clean? The loaves could be sticking to any residue.

Alternatively just shape into cobs and bake on a baking sheet instead. There's only the bottom in contact with metal then.
