Hi all,
The other day when cleaning the foil from our grill I put down the
foil which was was of greasy oil
from our delicious hamburgers. However some of it dripped on to the
concrete step area. It appears to have stained it (always looks wet
and dark).
I poured boiling water over it but to no avail still there. Are there
any other remedies to remove this unsightly spot.
Other than the obvious smart ass remarks like install new concrete
step or fry bacon on it. TIA. j/k.

Good old TSP was great, but not available in most areas today. You can
get special concrete cleaning materials. A power washer may work. Good old
dish detergent might even do it,

One favorite of mine is kitty litter and naphtha. Pour a little naphtha
on it to get it wet, add kitty litter to absorb it. Add more naphtha and
keep it wet for a while, then more kitty litter to absorb it until dry.
That usually gets most of it. Concrete is porous so it may be difficult to
get out.
