Gutters protect the siding of your home by catching water and draining it away from your home. However, these gutters also catch leaves, sticks, dirt and debris. When they become full, the water may flow from the gutters, causing the outside of the gutters to become dirty and stained. Even If the gutters are kept free of debris, outdoor elements such as rain and dust can still cause stains. After removing all debris from inside the gutters, clean the outside of the gutters to remove spots, stains and rust.
Things You'll Need
Liquid dish soap
Fill a bucket with a mild liquid soap, such as dish soap, laundry detergent or body wash.
Dip a nylon scrubbing brush into the soapy water. Scrub the gutters with the soap mixture to clean them. Rust, residue, dirt, buildup and corrosion can all be removed by scrubbing the gutters clean. These may require you to vigorously scrub, or make take several attempts, but it can all be removed.
Rinse the soapy water from the bucket. Refill it with water. Dip a sponge in the water. Wipe off the gutters to remove soap residue.
Never use abrasive scrubbers or harsh chemicals to clean a gutter. They can scrape, scratch and discolor the gutter.
