Lichen can be a common nuisance on outdoor wooden surfaces like decks, fences, and furniture. It’s not only unsightly but can also make wood slippery and even damage it over time.
So, if you’re wondering how to remove lichen from wood without causing harm, you’re in the right place. And the good news is, it’s not as difficult as you might think!
Instead, with a few simple steps and some common household items, you can easily get your wood looking fresh again. Read on to find out!
What is Lichen and Why Does it Grow on Wood?
Lichen is a combination of algae and fungus that forms a crusty, plant-like growth on surfaces such as wood. It thrives in damp, shaded environments, so if your wooden deck or furniture is in an area that doesn’t get much sun, it’s the perfect breeding ground for lichen.
The growth itself isn’t harmful to the wood in the short term, but if left untreated, it can trap moisture against the surface, which may lead to rotting or other damage. Plus, let’s face it—no one likes how it looks!

Essential Tools and Materials for Lichen Removal
Before we dive into the removal process, you’ll need to gather a few essential tools and materials. Here’s what you’ll need to safely and effectively remove lichen from wood:
- Soft-bristle brush or scrub brush
- Garden hose (or pressure washer, but on a low setting)
- Mild detergent or a specialized wood cleaner
- White vinegar (optional but effective)
- Gloves and a mask (for safety)
These items are all you need to get rid of that stubborn lichen without causing any harm to your wood.
Proven Steps to Remove Lichen from Wood for a Clean, Fresh Look
Now that you know what you’re up against, let’s break down how to tackle the problem step by step:
Step#1 Prepare the Area
First, clear the area. Move any furniture or objects away from the space you’re working on to avoid getting them dirty or wet. It’s also essential that the wood is dry before you start, as wet surfaces make lichen harder to remove.
Step#2 Gently Scrub the Surface
Using your soft-bristle brush, gently scrub the affected areas. Avoid using metal brushes or anything too abrasive, as they can scratch or damage the wood.
If the lichen is particularly stubborn, don’t worry—we’ll use a cleaning solution in the next step to break it down further.
Step#3 Apply a Cleaning Solution
Mix up a mild cleaning solution using warm water and a small amount of detergent. Alternatively, you can use a vinegar solution (1:1 ratio of vinegar and water).
Both options are safe for wood and effective at loosening the lichen’s grip. Apply the solution to the lichen and let it sit for about 10-15 minutes. This gives it time to soften the lichen and make scrubbing easier.
Step#4 Rinse and Scrub Again
After letting the cleaning solution work its magic, use a garden hose to rinse the wood thoroughly. If you have a pressure washer, set it to a low setting to avoid damaging the wood.
After rinsing, lightly scrub the area again with your brush to ensure all the lichen is gone.
Step#5 Final Rinse and Dry
Once you’re satisfied that the lichen is removed, give the wood one final rinse to wash away any remaining cleaning solution. Now, all you need to do is let the wood air dry completely.

Preventing Lichen Growth on Wood
Once your wood is lichen-free, you probably want to keep it that way! In that case, regular maintenance is the ultimate key to preventing them from coming back.
Here are a few tips to help:
Clean Regularly: A quick scrub and rinse every few months can prevent lichen from gaining a foothold.
Seal the Wood: Applying a wood sealant can help repel moisture and prevent lichen growth.
Increase Sun Exposure: If possible, move or trim back any plants that shade the wood to allow more sunlight. Lichen thrives in damp, shady areas, so sunlight is one of your best defenses.
Concluding Words
Removing lichen from wood is an essential part of maintaining your outdoor spaces and keeping them looking their best.
And by following these simple steps and using the right tools, you can effectively get rid of lichen and prevent it from coming back.
However, as always, regular cleaning and a little preventative care go a long way in maintaining the beauty and longevity of your wood surfaces.
