Storm drain run off restrictions / elamonator mix?

its NOT stucco, its dryvit and or EIFS

SH while its great for most cleanings its not the end all. I would have tried different chemicals if SH didnt do the trick.

I just wanted to say thank you all again for your help with this stubborn stucco or dryvit or whatever it was.

It looks much better now. Not perfect though. But I can’t get it to get any cleaner.

I ended up applying 12.5% SH from a pump sprayer - several layers with 10 min between applications and then rinsing with moderate pressure.
