A little background: my hubby and I both like to tinker with cars, and as a result our garage floor looks a little messier than we'd like. We finally invested in some actual spill cleaning supplies from a couple places like EcoAbsorb and SpillFix, and that's really cut down on the mess, but the old stains are still there. I am VERY against the idea of using kitty litter to clean things since I've read that this is bad for your lungs and the environment, which is why I invested in the eco-friendly cleaning supplies in the first place.

So with that in mind, I was wondering if anyone has any eco-friendly tips for cleaning old oil stains? It would be a big help!
