I never let it accumulate to any real volume. I have a grungy saucepan that I dump it into and let it evaporate the water off. If I get too much at one time, then the stove speeds that evaporation, but that is unusual as typically it just sits on my outside work bench and let the climate dry it out.

Then it is a simple task to use a paper towel to wipe up the gummy residue, sometimes a little alcohol helps with this, and then use the gunky paper towel as fire starter in my wood stove in season.
