    That would be fine. I'm not a green wash fan.

    We actually use up to 15 for a 50 gal mix

    I have not tried anything else but greenwash , it works well for me. im washing asphalt shingles, hardy plank siding and vinyl siding mostly....5-6 gallons 12.5 bleach works extremely well for me on siding. I mix 12 gallons bleach and one quart greenwash in a 55 gallon tank for roofs with great results, in warm weather but I am still learning.....what is the benefit of using up to 15 gallons bleach in a 55 gallon tank?....

    So I stumbled across this post. I am looking to experiment with "soft washing" a mossy roof with black algae streaks on it. I planned on using either:
    Green wash
    Supreme by safe wash
    or roof cleaner by safe wash

    So, to the people referring to green wash...is that the same stuff as I posted?
    Also can anyone comment on using "supreme" or "roof cleaner".
    I was not planing on using bleach. Should I?
    I plant on buying chemical soon and testing on my own house first.

    Green wash is unnecessary. But that's it.

    You need to use bleach. I used 15 gallons to 50 gallons of water. 12.5% bleach I think

    I used the Apple sauce mix. Biggest thing is keeping water running on all the plants while you're working. Especially along the gutter line. I plugged downsprouts

    Ok, thanks
    So I am assuming you mix in a 100 gal tank?
    What do you use to plug the gutters with?
    Would hooking up to the downspout and diverting waterflow away from lawn work better?
    If you don't water plants and lawn are they guaranteed to die or is that just a possibility?

    50 gallon tank. Brought 30 gallon drums of sh. 15/gallons of sh rest water. 3 or 4 bottles of gain

    I plugged the downspouts with nerf balls

    Also used sprinklers to keep everything wet. It'll at least make plants curl back. Why take a chance
