How to get this black stainrd mold, mildew, grime off concrete step?

First step before entering the house has this nasty build up.
I've tried power washing (15 degree tip) with a pretty powerful washer, but no luck - it did remove much of the green coloring - but the black is stubborn as heck.
I tried spraying with slightly diluted vinegar, scrubbing it in, and then washing again, but again only the green is consistently coming off.
Any clue? I'm at a loss and don't want to use harsh chemicals that could damage things. But willing to if it's a must.
Cheers!
