Have you tried oxi-clean it is non toxic and works wonders. Spray it on let sit till almost dry use a deck brush and rinse with water.
How do you remove tree sap from a concrete patio? It's older rough concrete. I've used bleach, Comet, and concrete cleaner. Nothing works. I've scrubbed until my back ached.

Stir the Zorb-All a bit after an hour or two, and then let it sit overnight. In the morning you can sweep it up, and all oil and sap stains will be gone. Have FUN! DearWebby http://webby.com/humor (08/12/2009)
