How to Remove Moss and Mold on Your Fence

Quality fencing adds value and beauty to your property. But over time, maintenance will be required to keep your fence looking new.


If you live in a warm, humid climate, moss and mold growth is an issue. Premier Fence offers these tips to help you navigate moss and mold on fence material.


First Steps for Cleaning Moss and Mold on Fence Material


  1. Cleaning solutions require a mask, goggles, and gloves for safety.


  1. Start by cleaning your fence in sections.


  1. Use the least abrasive cleaning solution first.


  1. Test in a small spot before cleaning a larger area.


  1. Always rinse thoroughly after cleaning.


  1. Make your hard work count. Seal your fence after cleaning to preserve its beauty and deter mold and mildew growth.


Cleaning by Fence Type




Wood is porous and organic, providing the ideal environment and nutrients for moss and mildew growth.


●      For mild cases, scrub with a stiff brush and soapy water.


●      For a more robust solution, use a 50/50 vinegar and water mixture. Let sit for 20 minutes, then scrub and rinse.


●      To eliminate tough stains, a baking soda paste is excellent. Apply, let sit for a few minutes, scrub, and rinse.


●      A low-pressure washer setting will also work, but be careful not to damage wood. Follow with a vinegar or bleach rinse.


●      You can also use a specially formulated fence cleaner.


Vinyl Fencing:


Moss doesn’t easily adhere to a vinyl fence, but it can cling to dirt and algae buildup, so cleaning will eliminate possible problems.


●      Use a mild dish soap and water solution for gentle cleaning.


●      After cleaning, apply 1 part vinegar/4 parts water to brighten the vinyl and remove lasting soap residue.


●      Like a wood fence, a baking soda paste will help with stubborn stains. Let sit for 10 minutes, then rinse.


●      A pressure washer can also be used with a wide spray nozzle and a low-pressure setting.


Brick and Stone Fences:


Moss and mold on fence materials of this type are a big problem because the rough surface and crevices encourage moss growth.


●      Start with dry brushing visible moss and mold with a stiff brush.


●      Use a mild detergent to scrub infected areas.


●      If you need a tougher solution, use 1 part bleach/4 parts water and apply with a sponge. Rinse after.


●      A moss/mold commercial cleaner will also work.


●      Use a low-pressure setting and fan nozzle on a pressure washer for tough growth.


Metal Fences:


Like other materials, with aluminum/metal, start with warm, soapy water and clean with a sponge. You can also use equal parts vinegar/water, let sit for 10 minutes, and rinse.


Make a baking soda/water paste, apply, scrub, and rinse for stubborn stains, or use a specially formulated cleaner. A pressure washer on a low setting also works.


Prevention is key. Regular cleaning and sealing will keep your fence looking beautiful year after year.
