How to Remove Moss and Mold on a Wood Fence

During warmer weather, wood fences often acquire mold, mildew, or even moss. It’s important to remove mold, mildew, and moss quickly because they are very unsightly and can greatly reduce the life expectancy of your fence.

Fortunately there are a couple of different solutions that you can use. It’s a good idea to clean your fence in the fall before harsher winter weather settles in, and again in the spring (if needed).

There are some easy mold removal solutions that you can use to remove mold, mildew, and moss. These solutions work best when you use them in conjunction with pressure washing. 

You can make an easy homemade fence cleaning solution. Add 1/2 a cup of vinegar per gallon of water and apply the solution. Let it sit for 15 minutes and then rinse it off. Baking soda is also effective as a pre-soak. Another solution is to add 1/4 cup bleach and 1/4 cup of laundry detergent per gallon of water while pressure washing. This can get most stubborn mold, mildew, or moss off your wood. 

If these solutions don’t work, or you would rather not mix your own solution, you can also try a commercial fence cleaner. A good one to try is Simple Green Deck and Fence Cleaner. You can buy it at most hardware stores.  You can even use Simple Green if you’re going in with a scrub brush and a bucket instead of with a pressure washer.

Always test any cleaning solution you use on a small section of your fence to make sure that the wood will not react badly to it. If it does, try a different solution. 

Don’t forget to tie back your plants before you begin. Many mold-killing solutions can do significant damage to your landscaping if you don’t take this simple, yet vital step. You should also work on a sunny day. Mold, moss, and mildew thrive under wet conditions. The sun will dry your fence off faster when working with these solutions, ensuring that you don’t leave conditions that are ripe for the growth to come back.
