So, shortly after posting my "Computer Chair" thread I noticed a smell of gasoline in the house, so I go sniffing around trying to find the source. Eventually I'm led to the unfinished half of the basement... where a a nice big oil spill is waiting for me. There was a substantial leak, I wake my dad up (cue "You live in your parents' basement" quips) and we get the leak stopped and mop up the mess for the most part.

In hindsight, we should've gotten pictures and called the oil company, our insurance company, etc., but now we're left with a stain on the concrete in our basement. Does anyone know of a publicly available product that would help clean up the remainder of the spill? Or, if not that, can anyone recommend a company that cleans up these kinds of spills?

(Side Note: I think this is a personal record for new threads created in one night.)
