Finally got my backyard patio pressure washed after 2 years

I put it off forever, but last Saturday I rented a surface cleaner from Sunbelt Rentals on Memorial Drive. Took about 3 hours and the difference is night and day. Has anyone else had luck getting old moss stains off concrete without damaging it?

I actually had a different experience with pressure washing on concrete. That surface cleaner can be pretty aggressive if you're not careful, I ended up with some etching in my old driveway that I'm still kicking myself over. Maybe try a gentler approach like a stiff brush and diluted bleach for those moss stains next time.

Wait, the surface cleaner actually etched your concrete?
