Dirt, pollutants, and environmental debris accumulate on the surface of gutters, creating unsightly black streaks that can damage your gutter system over time. Raindrops leave airborne pollutants on the aluminum gutters, which bond with the surfaces through electrostatic attraction, causing fine particulate matter to embed on the gutters. You cannot powerwash black streaks off of your gutters. Water runoff overflowing to the side of the gutters carries asphalt from the roof shingles, which chemically bonds with the aluminum gutters and results in tiger or zebra stripes. Handle and use the Gutter Guard gutter cleaning chemical with caution and do not use it on polished or anodized aluminum. DIRECTIONS FOR USE: Gutter Guard Gutter Cleaner is super concentrated. That translates to attractive product for shipping and cost. Dilute it with 2 parts water to 1 part product and up to 3 parts water to 1 part product. Do not use on polished or anodized aluminum.
