Hi, Can you please help me with what I can do to restore/prepare parts of crinoid matrix that has eroded. This piece has been in the storage for several years wrapped up, and after taking it out for display, I have noticed small sections of the matrix started to come off in fine dust. What kind preparation is needed to seal/restore the light coloured exposed matrix surface to its original darker colour? Thanks in advance.
