I live in Florida and we have lots of Oak trees and would like some advice as to the best solution to use when cleaning concrete surfaces that are heavily stained with Oak Tree sap. Thanks

Strong Bleach will work. Watch them disappear.
 
I have not ran into that yet, but want to be prepared.
Is that first picture after you pre treated and ran over with a surface cleaner?
After do you just go back with like a 50/50 mix in a pump up then surface clean again or the 50/50 Sh knocks it out?

First picture is after surface cleaning & Pre treated Downstreaming 10% SH full strength w an 8 Gpm machine through 200 feet of hose.

2nd pic is after two treatments Downstreaming 10% SH full strength w an 8 Gpm machine through 200 feet of hose. Mix doesn't have to be real strong. Just be patient and let it dwell.
