I've used acetone for cleaning up mixed epoxy -- I assume this would also work for the individual components. Recently someone here said that plain ol' vinegar works just as well and doesn't requre ventilation (unless you just don't like the smell of vinegar.) After finishing my boat last spring I didn't bother to take out the pumps from the jugs. Just last week, after 6 months on the shelf, I made up a small batch, and they worked fine. They hadn't even drained back into the jugs.
