I was cleaning out my little shed today when I find that my husband left two entire gallons of used car oil in there. Said oil was in a plastic milk bottles, one of which has split and the whole gallon is now all over the cement floor.

How do I clean it up?

Cat litter does a good job of soaking up the spilled oil. You can pick up some enzymatic cleanes at auto supply stores that eat the oil and leave non-toxic reidues that are easliy cleaned up.
