4. Steps to Remove Mildew and Lichen:

Step 1: Preparation:

  • Put on protective gear such as gloves, goggles, and a mask to protect yourself from exposure to cleaning chemicals.
  • Clear any debris or vegetation from around the fence to ensure easy access and prevent interference with the cleaning process.
  • Test the chosen cleaning solution on a small, inconspicuous area of the fence to ensure it does not cause damage or discoloration.

Step 2: Mixing the Cleaning Solution:

  • For a homemade cleaning solution, mix one part bleach or oxygenated bleach with four parts water in a bucket or sprayer. Alternatively, you can use vinegar or borax diluted in water as a natural cleaning alternative.
  • If using a commercial mildew remover, follow the manufacturer’s instructions for dilution and application.

Step 3: Application:

  • Apply the cleaning solution to the affected areas of the wooden fence using a scrub brush or pressure washer. Work in small sections to ensure thorough coverage.
  • Allow the cleaning solution to sit on the surface of the fence for 10-15 minutes to penetrate and loosen the mildew and lichen.

Step 4: Scrubbing:

  • Use a scrub brush or pressure washer to scrub the surface of the fence and remove the loosened mildew and lichen. Work in a circular motion, paying extra attention to heavily affected areas.

Step 5: Rinse and Repeat (if necessary):

  • Rinse the fence thoroughly with clean water to remove any remaining cleaning solution and debris.
  • If mildew and lichen persist, repeat the cleaning process as needed until the fence is clean and free of contaminants.

Step 6: Final Inspection and Maintenance:

  • Once the fence is clean, inspect the surface for any remaining traces of mildew or lichen. Touch up any missed spots as needed.
  • Consider applying a protective sealant or stain to the wooden fence to prevent future growth of mildew and lichen and prolong its lifespan.

In conclusion, removing mildew and lichen from a wooden fence requires the right materials, techniques, and precautions to achieve effective results. By following these steps and taking the necessary precautions, you can restore your wooden fence to its original condition and protect it from further damage. If professional services are needed, be sure to obtain quotes from multiple providers and choose one that offers quality service at a reasonable cost.
