3 Effective Ways to Remove Lichen from a Wooden Fence

A fence not only makes your home look aesthetically-pleasing but also adds security and protection to your property. There are many types of fences, one of which is made of wood.

Wooden fences are a popular choice of fence material among homeowners. It can be a cheaper fence material, unlike PVC, aluminium, or metal. You can also paint it in your preferred color. Unfortunately, wooden fences are prone to mold and lichen which not only are unattractive to look at but also affect the quality of the wooden fence.

Most people would think that the best option is to replace the fence, which means additional expense on your part. But there is good news for you – there is no need to buy a new fence. All it takes is proper cleaning to make your dirty fence look brand-new again. 

Tip #1: Scrubbing by hand 

Before going ahead and scrubbing your mildew and lichen-infested wooden fence, make sure to cover the surrounding plants first. Use old tarps or inverted buckets to cover the plants and shrubs nearby. 

Next, mix one-part chlorine bleach, two parts warm water, and a teaspoon of liquid soap for every gallon of water. Make sure that the soap is safe to combine with the bleach. Then scrub the fence using a scrub brush and rinse with clean water afterward. 

Tip #2: Using a power washer 

Power washing can also help in removing unsightly dirt and mold off the fence. Make sure you also cover the plants and shrubs near the fenced area first. Next, set your power washer around 1500 to 2000 psi. Stand about 2 feet away from the fence and start cleaning the fence.

Move the washer in slow, up-down motion. For heavy and stubborn mildew stains, you can move closer to give it some thorough cleaning. Or scrub the area after spraying for some “finishing touches”. 

Tip #3: Controlling lichen and mold growth

Lichens tend to grow and spread slowly especially in moist areas. One way to lessen the growth of lichens is by moving the sprinklers or irrigation lines away from the fence. You can also scrub off lichens just when they are about to form and grow. Increased airflow and sunlight can also help in lessening the formation of lichens.

After removing the dirt and lichens of the fence, check whether it also needs some repair. Sand the rough areas when needed. If there are protruding screws or nails, repair it immediately to avoid possible injuries later on. 

After cleaning the fence of the lichens, let it dry first before applying the wood preservative. This will help make your wooden fence more resistant against the harsh outdoor elements. Adding wood stain or repainting it can make the fence look more refreshing than before. 


Cleaning your wooden fence and restoring it to its former glory need not be expensive. It’s a matter of proper cleaning, care, and maintenance. Repainting is also a good idea for good-looking fences all the time!
