Mildew growth on rain gutters is unsightly. Luckily, it's also avoidable. With basic cleaning products and proper maintenance, you can remove the mildew from your gutters and keep it away when you're done.
What can you do to remove mold and mildew from your rain gutters?
Mix together equal parts vinegar and water into a bucket, then dip a sponge into the solution and wipe down the gutters with the sponge. Let the solution soak on the gutters for a few minutes (much of it will drip off, but this is alright) while you fill a spray bottle with the vinegar and water. Then, spray the gutters with the vinegar and water solution. Use a soft bristle scrub brush to scrub away the mildew. When you're finished, use a strong jet of water from a hose to rinse the last of the vinegar off of the gutters. Don't use a power washer, as this may damage the rain gutters or cause them to become loose.
What can you do to prevent the mold and mildew from returning?
Mold and mildew grows best in places where it is dark, moist and cool. To prevent mold from becoming a regular problem, you can do the following:
- Clean the gutters in the fall and the spring. Clogged gutters can overflow when it rains. This constant presence of moisture during storms and after the rain stops can promote the growth of mold on your gutters. It's important to clean your gutters out during the fall, when leaves and other debris can easily cause clogs. Cleaning again in the spring will clear away petals, seeds and other litter. This prevents blockages and will help ensure that water flows properly.
- Cut back overhanging tree branches. Overhanging tree branches can cause a variety of problems for your gutters. In addition to dropping debris into the gutters themselves, overhanging branches release big drops of water onto your gutters after storms end, and can also cast your gutters into deep shade throughout the day. Removing overhanging branches will make the conditions less favorable for mildew growth.
- Keep your rain gutters in good repair. Sagging gutters can easily overflow, creating the moist conditions that encourage mildew growth. Getting regular maintenance on your gutters will help you avoid these problems.
