Acid does a lot of things, but it will not clean grease or oil!  You need a
base (lye)type cleaner or solvent (byutal) type cleaner to remove grease or
oil.  Then you can use an acid to whiten the concrete.  I use Gunk, or
carborator cleaner to remove the oil, then a mild acid and elbow grease to
whiten the concrete.

DO NOT MIX CHEMICALS THAT ARE NOT INTENDED TO BE MIXED!!!

WEAR SAFETY CLOTHS AND EYE PROTECTION!
