I haven't tried the product you asked about but I have used Tide
laundry detergent granules on concrete. I used to wet the oil spot and
sprinkle on the Tide. Then let it sit overnight, sweep and hose it off
in the morning. I once left it on too long and wound up with a lighter
spot than the surrounding area. I think it's the bleach that does the
whitening.
Cheers,
CR
