I would double the bleach. Depending on how high and how many spots you need to do, I would use a pump sprayer if it is a small area. I have the portable sprayer from powerwashstore.com with shurflo pump that I use - no problems. Just rinse with bleach wash 1 cup per 5 gallons or so. I would use bleachwash on windows. It works plus it is a selling feature.
The aluminum store front window below is anodized and may streak or spot from bleach exposure. Make absolutely sure that you keep it continuously wet or cover it with plastic. Other than that I would use a 1% mix HEAVY with green wash.
Hey Vic use the blue tape I can't remember what is called but we used that for outlets railings etc. with a plastic trap basically anything that we didn't want paint to fall on when we were doing commercial buildings as far as the water on the plastic as long as you secure it right the water should just roll off hope this helps!

Our general rule here is to start weak and then bump it up as you need it. It is easier to add strength to a mix but harder to take it away. Start low and then go up as you clear up room in the tank spraying. Our SoftWash Systems Cradle Skids allow us to add concentrate while spraying and agitating.
Thank you, Alejandro. Are you talking about painters blue tape? Will that hold up with the Ducksauce?
I know I don't want it flowing, need a mist, not a river, but don't want the plastic falling, either.
I'm sure there will probably be several coats and the rinses will wet it, also.
I have a couple more places I'll need to use this, also, on another part of the same building!
These are more like lava flows, and would be a challenge for anybody, but especially a newby like myself...
OK, forget fantasy football. How many coats of 1% would these take (see pictures)? 2%? I won't try 3% as I don't want to risk messing up the aluminum window frames.
