Floor dry, of saw dust. Sweep it up and put into a paper bag. Throw the bag and contents into the wood stove. Burn it when there is a chill in the air. (like today ;-)
Put down another light coat of floor dry or saw dust and just leave it sit on the spot for a day or two to pull up the residue. Or. spray the area with brake cleaner. and dry it up.
Was mixing vegetation killer with diesel, had small spill, butane torch wouldn't light it. Placed paper towel on it and it burned like a wick in a kerosene heater. I'm stocked up on oil dry now.
Barber Motorsports Park in Birmingham/Leeds Alabama shocked the Dawn guys when they called asking about ordering in bulk. Seriously, they found Dawn was the best thing for cleaning oil spills on the track.
