Pressure Washing Guide

I've noticed concrete under trees can be very difficult to clean.
Lots of times once you clean up all the algae, mold and dirt you have these little green round spots that just seem not to come up.
I've even used strait bleach day after day applications trying to get them up.

Any suggestions?

Also with all the rain we've had here in the southeast pressure washing will be a gold mine for 2009-2010

I leave them if they don't come up with strong bleach mix, high pressure, and hot water. It doesn't happen often but I have had that happen on occasion.

Most of the time if you work each individual spot up with the wand like you would with gum, they will come up. Other than that there isn't much you can do.

I know this will come as a shock to some people, but a pressure washer and chemicals will not always remove every single stain. People have looked at me cross-eyed sometimes when I can't get off paint splatter, tar, caulk, or radiator rust. It isn't a magic wand I tell them, its a pressure washing wand.
