Gutter Grenade

My guys notice a considerable degredation of the mix after a gutter cleaning. We have tried to use it a few days after cleaning some nasty gutters only to find out that it doesn't seem to do so well on just slightly dirty gutters. I try to make sure that we don't mix up any more than we need to do a job. In fact, I would rather have to mix up more to complete a job than have cleaner left over.

I will have to order another 5 gallon pail of F-13 soon as I am down to my last half gallon. That stuff works pretty good!
 
Do you have to scrub the gutters using F-13 of it depends how dirty they are?

Not spray and rinse?
 
scrub, scrub,scrub
 
That's weird. I bought some F 13 a few times and really loved it at first. Then one day it just seemed like it stopped working. I don't know what could have happened. I figured it had a limited shelf life. I don't figure it's gotten cold enough here in Florida to freeze the stuff.
