I pour on some gasoline, scrub it with a brush, then throw on some oil sorb.
brush it back and forth, let it sit and then brush it back and forth again.
Sweep it up.
As mentioned, the soot in the oil will be a problem to remove.
After you get it as clean as you can, wet the concrete and throw on some
of the powder cement, wet it and brush it into the concrete.
After it is dry, it just might blend in and hid your sins and apease the pita
HOA.
Iam the HOA around here.
Just for fun, pour some black engine oil under one of the HOA stool Pigeons
cars. Sit back and watch the fun.
