well I also have a Grandson and I like giving him something to do around my place instead of playing Video Games on the couch when he comes…AS I said, I will paint the gutter if not done when I go back,
I use a hot house wash mix
1 gallon S/H
1/4 glln EBC
1 glln water
Spray on with pump up sprayer
Light brush
Rinse
Done
I use awesome and it works great. Spray it on: one part awesome and 2-5 parts water, depending on how bad it is and how hot it is outside. wash off with a hose before the paint comes off. It will take the first layer of paint off along with the streaks. Finish job looks like new gutters if done right.
