Lichen can grow on just about anything outdoors. It tends to thrive in areas with high humidity and limited sunlight, making outdoor furniture a prime location for lichen to grow. Lichen can be unsightly and difficult to remove, which is why we have put together this guide to help you remove lichen from your outdoor furniture.

Step 1: Gather Supplies

Before starting the cleaning process, make sure you have all the necessary supplies. You will need a soft-bristled brush, such as a toothbrush or a scrub brush, white vinegar, and warm water. It is important to use a soft-bristled brush to prevent damaging the surface of the furniture.

Step 2: Mix Cleaning Solution

Mix equal parts of white vinegar and warm water in a bucket or spray bottle. The acidity in the vinegar helps to kill the lichen and loosen its grip on the surface of your outdoor furniture.

Step 3: Apply Cleaning Solution

Once the cleaning solution is mixed, apply it to the affected areas of your outdoor furniture. It is essential to coat the entire area with the cleaning solution, allowing it to sit for 10-15 minutes. This will allow the vinegar solution to penetrate the lichen and loosen it from the surface of the furniture.

Step 4: Scrub Affected Areas

After the cleaning solution has had time to sit, gently scrub the affected areas with your soft-bristled brush. Be careful not to scrub too hard, as this can damage the surface of the furniture. Rinse the area thoroughly with warm water to remove any remaining lichen and cleaning solution.

Step 5: Prevention

Once the lichen has been removed from your outdoor furniture, it is essential to take preventative measures to ensure that it does not grow back. This includes keeping it dry and clean, as lichen thrives in moist environments. Use a cover to protect your outdoor furniture during periods of rainfall or high humidity. Additionally, make sure to clean your outdoor furniture regularly to prevent the accumulation of dirt and debris, which can attract lichen.


Lichen can be a nuisance when it comes to outdoor furniture, but with the right supplies and cleaning techniques, it can be easily removed. Remember to take preventative measures to ensure that lichen does not grow back. By following these steps, you can keep your outdoor furniture looking clean and vibrant for years to come.
