10 Easy Steps on How to Remove Lichen From Stone
Step 1. Use Safety Gear:
Put on your protective gear before beginning the process, especially when using an acid based cleaner. You can also wear a mask to protect your lungs from any particles. It will also prevent you from getting any chemicals in your eyes.
Step 2. Remove Excess Dirt:
Use a stiff brush to loosen any dirt or debris from the stone’s surface. Be careful not to scrub too hard, as this can cause damage. Otherwise, brush away any debris until the stone’s surface is clean.
Step 3. Mix Detergent and Water:
Create a mild detergent in a bucket by mixing warm water and a mild detergent such as dish soap. Ensure the detergent does not contain any bleach or other harsh chemicals. Because the detergent is mild, it will not damage the stone but rather act as a cleaning agent to help remove any dirt or debris.
Step 4. Apply Detergent Mixture:
Saturate the lichen with this soapy mixture using a garden sprayer or by pouring it directly onto the lichen covered area. Another option is using a soft bristle brush or sponge to spread the soapy mixture. It Is important to saturate the lichen so it can be removed more easily.
Step 5. Wait 10 to 15 Minutes:
Allow the soapy mixture to sit on the lichen for 10-15 minutes. This will help to loosen the lichen from the stone, making it easier to remove. Keep the mixture from sitting for too long, however, as it may damage the surface of your stone.
Step 6. Scrub Away Lichen:
Using your stiff brush, scrub away the softened lichen carefully. Try not to damage the stone’s surface as you do this by applying pressure gently and in circular motions. Be sure to rinse off any dirt or debris that is loosened during this step.
Step 7. Rinse Surface with Water:
Rinse the area thoroughly with water until all traces of detergent have been removed. This will help prevent any residue from remaining on the surface. Keep in mind that some residue may remain, however, it will be minimal.
Step 8 . Use an Acid-Based Cleaner:
If any lichen remains after steps 1 through 7, try using a dash of vinegar or other acid-based cleaners to remove it. Apply the cleaner in the same manner as you did with the detergent and scrub away any remaining lichen with a brush. Always follow the instructions carefully when using an acid-based cleaner, and wear protective gear.
Step 9. Rinse Again:
Rinse the surface again with water once to ensure all traces of cleaning solutions have been removed. And that’s it! You’ve now successfully removed lichen from your stone without damaging its surface. With simple supplies and a few easy steps, you can keep your stones looking beautiful for years to come!

What Causes Lichen Growth?
Lichen growth is caused by air pollution, moisture, and other environmental factors. It can grow on any stone or rock surface, including brick, concrete, and flagstone. Lichens are an example of a symbiotic relationship between fungi and algae.
They form when spores from the fungi land in wet conditions on surfaces with little to no wind. If these conditions persist, lichens will begin to form on the surface of your stones.
Additionally, lichens can form due to inadequate care and maintenance. It is important to regularly clean your stone surfaces with soap and water, as well as apply a sealant to protect the stones from future lichen growth.
By understanding the causes of lichen growth, you can take preventative measures to avoid it in the first place! Keep your stones looking beautiful for years by following these simple steps and tips.
Is Lichen Harmful to Humans?
No, lichen itself is not usually harmful to humans. The main problem with lichens is that they can cause discoloration and damage to stone surfaces over time if left untreated. Additionally, some species of lichen have been known to produce toxins that may be hazardous if ingested or inhaled in high concentrations.
It is best to take preventive measures to avoid lichen growth, such as regularly cleaning your stones with soap and water and applying a sealant for extra protection. If you are dealing with a lichen problem, follow the steps outlined earlier in this article for safe removal without damaging your stone.
