People on forums who don't know the answer but say go ask somewhere else always annoy me but occasionally I do it myself and feel a bit ashamed of what I have just done.

I'm guessing, if you are in the US, there is a AutoZone, PepBoys or Kragen's nearby.

Were I to have the problem you described I would ask someone there. Not everyone who works these places is knowledgeable but some will be. Some of their websites boast of "tips".

That's a good and helpful answer, Albert, because those stores sell the kitty-litter type stuff that you pour on and soak up the oil and grease.

Kitty-litter will soak up the grease/liquid mix. It may take a week or so for it to pull up what it can.

After the litter stops absorbing the oil, use a dab of dish soap on a rag (do not mix any water with it- just straight soap on the oil spot) Rub it in good with a scrub brush, then break out the hose. If you are not able to hose out the garage use something less bubbly such as Simple Green- just use full strength and no water until you get worked into the spot good.

Thanks. I'll make DH do it LOL.
