More hardiplank questions. Best way to clean mold/algae/grass stains

The joys of a light colored house.
I hit some spot with the pressure washer at 40deg but that didn't do jack and I don't want to go with more pressure. Damage the plank or remove the paint.
So I guess I will be hand cleaning tomorrow, any recommendations on a cleaning solution?
Thanks in advance.

You could try Jomax which you mix with bleach.
If stain remains, time to break out the paint brush or roller.

I've been pleased with 30 Seconds cleaner.

This stuff is my go-to for mold and mildew, works great and no pressure washer needed.

You shouldn’t be pressure washing hardieboard.
Softwash with a light bleach solution and soap.

softwash
10% pool bleach

dash of dawn soap
Wet the area with water first, spray softwash solution, let it set for 15 mins, spray off. works great for my house

Just to echo solid advice: Jomax + Bleach
