.Went out to give estimate just to clean the stone on the front. The bleach I used might have been weak. Nothing happened after applying ot straight with a brush. Then adsded Gutter cleaner. Nothing. Then also added The Right Stuff degreaser I had laying around & some Sodium Hydroxide. No good. Any ideas. I am going to pump out some fresh SH and test it again.

Yea,..would be nice to see the pictures! I love evaluating mystery stains, Ha, Ha,..Something to try in the meantime is an aluminum brightener with Hydrofluoric Acid. Small test spot obviously,..but often time stone can be cleaned with it. If it's not mold,..which considering your bleach test it isn't,.....it's likely atmospheric???
Did direct high PSI do anything,..or didn't you try that?
Sometimes stone just ages funny and it is what it is? Sounds like this can be cleaned though.
PICTURES! PICTUTRES! PICTURES! Ha, Ha,....

I've try to do some sandstone several times where the black mold is so embedded nothing gets it out.
think I poured straight 12% and pushed it around to dwell and got some but not all out
