I have two questions. I have been doing power washing for quite a few years, and have been doing most of my jobs from the ground the past two (no ladders). Since I am not on a ladder I am having trouble getting gutter streaks out. I Jet-ex the house and gutters with a clorox, detergent mix and let it dwell for 5-10 minutes. I then power wash the house with an extension wand at approximately 3000 psi. I had less or no streaks when I was on a ladder and able brush the gutters from around 6-7 feet. Is there any products for this issue I am having?
My second question is about the little black dots that form on the sides of houses. Where the heck do the come from and how do you get rid of them easily? I read here not too long ago that they were from an algea that came from mulch. I also heard they come from insect matter. Any ideas out there?
