I am gluing some copper to wood with CA. Anyone knows how to get rid

I understand that there may be a way to avoid getting the white stuff
by not using so much of the accelerator but is there any way to get
rid of it *after* the fact?

Yeah, don't use the accelerator.

What he said. Accelerator active ingredient is N,N-dimethyl
p-toluidene, a tertiary amine. Amines react with copper to form
quaternary amine complexes. In other words, they eat copper.
