Ask your wife how it works for removing the nail polish ?
I had tried some off brand bought from the drug store by wife, she was going to throw it in the garbage can ( cost 99 cents ). I used it for cleaning up stuff and it did not work as good as the regular acetone. Some cases the gasoline works better, mineral spirits worked fine.
Get a nice tornado barrel brush , run it a couple of times after you soften the epoxy, is the best way to clean out the hosel.
