Oil stains on concrete

[John Larson]

"Anyone have any good product recommendations or home brew recipes for
getting oil off of concrete floors?
MAC, ...  Its from an overhaul I just did on my 4000TQ."

It may not, in these enlightened times, be politically correct, but lacquer
thinner is without a doubt one of the great concrete degreaser/stain
removers.  In the bad old days I cleaned entire concrete driveways with
lacquer thinner and a rag.  Might want to use a mask, lest you end up like
me .....  John
