Remove Debris And Rinse Off The Gutter System
Set up a ladder next to one end of the gutter system. Loosen debris that is in the interior part of the gutter system with a hand rake and throw it in the trash bag. Rinse the gutter system off with a water hose. Place the end of the hose inside the downspout's opening to rinse out the inside of it and remove any debris that is trapped inside. Removing the debris and rinsing off the gutter system will make it easier for you to locate all of the mildew in the following steps.
Remove the tank from a garden sprayer and fill it with equal amounts of bleach and water. Reattach the tank. Use a few pieces of plastic sheeting to cover grass and foliage that is located below the gutter system so that they are not exposed to the cleaning solution. Apply a liberal amount of the cleaning solution to the mildew by squeezing the trigger on the garden sprayer. Allow the solution to penetrate for several minutes.
Use a handheld scrub brush to assist with removing the mildew stains. Use more of the cleaning solution if you are having difficulty removing the mildew from portions of the gutter system. Rinse the gutter system off with a water hose once all of the mildew has been removed. Remove the pieces of plastic sheeting from the ground. Once the mildew has been eliminated, you will no longer need to worry about it spreading or damaging portions of the gutter system or your home's exterior.
Clean The Gutter System Throughout The Year
Mildew forms on surfaces that are moist and located in shady areas. To minimize the chance of mildew forming in the future, keep the gutter system clean throughout the year. Remove debris that can clog the gutter system and cause water to pool in parts of it. Use mild detergent and soapy water to remove surface stains from the gutters and rinse the entire system off with a water hose. Inspecting the system several times a year and cleaning it when necessary will keep it in great shape. You can also hire a professional gutter cleaning service if you don't have the tools to do it yourself.
