How to Remove Mold on a Fence

how ot remove mold on a fenceIn the springtime, wooden fences can 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.

Easy Mold Removers

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 your fence.

One solution involves adding 1/2 a cup of vinegar per gallon of water. You’d 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 would be 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 you can also try Simple Green Deck and Fence Cleaner. You can even use Simple Green if you’re going in with a scrub brush and a bucket instead of with a pressure washer.

Remember, you should 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.

Wet and Forget

If you don’t want to pressure wash there is an interesting product called Wet and Forget. You add the product to a simple sprayer and apply it to the fence.

As the name implies you then simply walk away and let it work. The solution kills mold, moss, and mildew, making your fence look beautiful once again.

You can pick up Wet and Forget at any hardware store if you don’t want to order it online.

Other Tips

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.
