Wood fences accumulate grime and dirt over time, which can be unsightly and also degrade the integrity of the fence. Fortunately, whether you want to use a power washer or clean it by hand, there are some simple steps you can take to wash off the dirt and scrub off other grime. Here’s how to clean your wood fence:
How to Power Wash your Wood Fence
Cleaning a wood fence with a power washer is much quicker than washing it by hand, but it can also damage your fence if you’re not careful. Follow these steps to make sure that you power wash your wooden fence correctly:
1. Remove Caked-On Gunk with a Wire Brush
There are certain kinds of grime that power washing won’t remove. Some you should scrub off before power washing and some you should remove afterwards. Before you power wash your wood fence, take a wire brush and gently scrub off caked-on grime such as mud. It’s especially important to be gentle when you have a painted fence because the wire brush may damage the paint.
2. Rinse your Wooden Fence with a Garden Hose
You want to prep your wood fence for pressure washing by first spraying down the entire fence with your garden hose. Set the hose to a medium-high pressure to get off some of the surface dirt.
3. Get your Pressure Washer Ready
It’s important to be careful when pressure washing a wood fence so that you don’t damage it. You want to use a pressure washer with a psi that’s no higher than 1500-2000. In addition, it’s a good idea to add a tip to the pressure washer that will fan out the water. A 25-degree tip is a good choice.
4. Use Long, Even Strokes to Clean your Wood Fence
To pressure wash your wood fence, you want to stand about 2 feet away from the fence and use long, even strokes. Spray from right to left and keep going until you no longer see dirty runoff coming from the fence.
Make sure that you don’t point the power washer at one particular spot for too long. The constant spray of water in a single spot can end up damaging your wooden fence. This is why it’s important to use long strokes to clean your fence.
How to Wash your Wood Fence by Hand
Hand-washing a wooden fence is a good option if you don’t own a pressure washer or you’re concerned about potentially damaging your fence. Here are some simple steps for hand washing a wood fence.
1. Prep the Fence
The first steps for hand-washing your fence are the same as for pressuring washing: scrub off caked-on gunk like mud with a metal brush and then rinse the fence with a garden hose.
2. Apply Oxygenated Bleach with a Paintbrush
Oxygenated bleach is a great tool for safely removing stains from exterior surfaces. Mix an oxygenated bleach powder with water (according to the directions on the container) and then begin to brush it onto the fence using a painter’s brush. You’ll want to use a large paintbrush so that you can get the job done quicker. Let the bleach set for 15 minutes
3. Scrub Off the Bleach
After the 15 minutes are up, use a plastic bristle scrub brush to scrub off the dirt.
4. Rinse your Wood Fence
Finally, you’ll want to use your garden hose to rinse the bleach off your wood fence.
How to Remove Stubborn Mold, Algae, Moss, and Mildew
After you pressure wash or hand wash your wooden fence, you may have some mold, moss, mildew, or algae left clinging to it. If so, here’s how to remove them:
Removing Mold and Algae
Mold and algae can damage your wood fence, and even if you remove them, they can leave behind green stains. To remove these growths, make a mixture of one part chlorine bleach and two parts water. Use a plastic bristle brush and this mixture to scrub the mold or algae off your fence. Once you’ve gotten the mold or algae up, rinse off all areas where they were with your garden hose.
Removing Moss and Mildew
Like mold and algae, moss and mildew are both damaging and unsightly to your fence. The solution to removing these growths is a bit different, however. To remove moss and mildew, you’ll want to use a mixture of ½ cup vinegar and 1 gallon of water. Apply the mixture to the wood fence with a sponge and let it sit for 15 minutes. After that, you’ll use a plastic bristle brush to scrub off the moss or mildew. And at the end, you’ll rinse off the spots you cleaned with your garden hose.
