You can adjust the formula s strength by diluting it either half and half with water or one part gutter zap to 3 parts water.
Electrostatic bonding gutters.
The dark marks on gutters are caused by the electrostatic bonding of dirt grime and acid rain runoff.
Use gutter zap on your new applicator to apply it to the exteriors of gutters.
Rinse it off and let those gutters shine.
Some professionals have said that the black streaks are also caused by the tar in asphalt shingles but this isn t likely because the streaks appear even on houses with metal or tile roofs.
When cleaning gutters it is important to break the bond between the dirt and gutters.
Your gutters are in a vulnerable area.
Over time these stains get embedded into the oxidized paint on the gutters.
The black streaks are a result of electrostatic bonding of tar asphalt from roofing material and other debris to aluminum metal material.
Gutters are metal and as such have an electrostatic bond which attracts atmospheric dirt.
Streak getter will break down this bond which will allow you to remove the unwanted streaks off your aluminum gutter with little effort no scrubbing.
They sit right at the bottom of your roofline and debris and dirt tend to cascade down your shingles and over the gutter system.
The contaminants will attach to the gutter oxidation in another process called electrostatic bonding and over time will cause those unwanted black streaks.
This is due to a phenomenon called electrostatic bonding.
