Sometime within the last several days someone sprayed sunscreen on our concrete patio. It left a goopy, dark, tacky stain and is over a fairly large area; maybe covering an area 3 x 5 feet. It is very unsightly and feels terrible to walk over - sort of sticky, but I also fear it will be slippery with wet feet.
Does anyone have any suggestions for how to remove this residue? I tried scrubbing dish detergent and Goo Gone, then hosing it off, but no success. If it matters, the concrete is tinted - the kind of tint that goes in the mix, not applied afterward, and the stained area is fairly close to the house.
