Have you tried whacking the outside where the resin is with a rubber
hammer? That might be enough to get it to flake off without causing
much damage.

I've got most of it out but I don't think anything mechanical will get
it out of the narrow sections and seams.



you can get a remover for that, personally never used it but told it does
work

Useful to know but a bit expensive.
