When we went to prep for sealing we discovered dozens of stains from tree matter that will not come up with pressure washer, simple green, or elbow grease. Looks like someone put a hundred tea bags on the patio. any suggestions? btw- this forum rocks. thanks for all the time you guys invest in it.

I have since learned to research rather than react. There are people that make a living creating cleaning products for specific types of stains(LOL) Prosoco BioKlean worked like a charm

If some of the release color is removed during the clean up process you can always go back with an antiquing solution and touch it up. Art

Solvents and acids will often have little effect on these type of stains,they seem to react more with the concrete matrix than some pain in the ass brown stains on a nice slab. Good luck.
