Removing ashes of 3d printing resin

I'm not a chemist so excuse me if my question will bite your eye or ear.


A resin 3d printing uses polymers that cure under exposure to UV light. There is a special sort of 3d printing resins made for casting metals. Basically these resins produce smaller amount of ash during casting. I'm looking for a way to clean-out a metallic part made from aluminium (or other metals in a list below) from 3d printing-resin-ash that occurs in place of contact with metal.


I'm unable to apply mechanical force to clean out the model due to it's geometry so naturally I would like dissolve the remnants of polymer (supposedly carbon) with some sort of acid or anything else that would eat-out ash while preserving metal as much as feasible.


The list of metals can be any of the following:


Aluminum, chrome, copper, nickel, steel, silver (ordered from most preferable to least preferable)


Is there a chemical compound capable of achieving the goal.


Thank you in advance!
