Which is much easier than dealing with mineral spirits.  Most places,
you simply allow the water to evaporate, and dispose of the solids.
Places with air pollution restrictions on that, you skim the oil from
the top, settle and filter the solids out of the aqueous phase, and
dispose of them.  the aqueous phase is waste water, unless it's ph is
too high, or it contains substantial heavy metal, which isn't usually
true of most home use.
