Tree Sap on Concrete

[One Tough Pressure 580]

Tree sap on concrete has been a tough one in the past. I have tried Bug and Tar remover, Alcohol, and degreaser, coupled with 210 degree water on a very hot day. After spending way to long on some small spots, it finally gave in, but their has to be a faster way. Anyone have some input as to a chemical that will help the process?

Still got that HD-80 sample? Tree sap is resin. Resin is found in sealers....HD-80 breaks down the resins found in sealers. Give it a shot.

Yes, I still have the sample. I was planning on testing it on some wood projects that I have around the house, but have not gotten around to them.

I did not even think about using that, but will have to find some sap and give it a try. Sometimes the answer is so close, I don't even see it.
