Master cedar fence cleaning with our pro tips. Learn how to brighten your fence, remove stains, and restore its natural shine.

Cedar fences are a popular choice for homeowners due to their natural beauty, durability, and pleasant aroma. However, over time, cedar wood can lose its luster due to exposure to the elements. If you’re looking to restore and brighten your cedar fence, it’s essential to know how to clean it properly. In this guide, we’ll share the best cedar fence cleaning techniques and secrets that will help you keep your fence looking fresh and vibrant for years.
Why Clean a Cedar Fence?
Cedar wood is naturally resistant to decay, but it still requires regular maintenance to keep it in top condition. Dirt, algae, mold, and mildew can accumulate on the surface, causing discoloration and damaging the wood. By learning how to clean a cedar fence, you can remove these impurities and extend the life of your fence.
Cleaning your cedar fence offers several benefits:
- Restores Natural Beauty: Regular cleaning can bring out the natural color and grain of the cedar wood.
- Protects Against Damage: Cleaning helps prevent mold, mildew, and rot from taking hold, which can compromise the structure of your fence.
- Prepares for Staining or Sealing: Proper cleaning is crucial if you plan to stain or seal your cedar fence, ensuring better adhesion and longer-lasting results.
Step 1: Gather the Necessary Tools and Supplies
Before you start cleaning, it’s essential to have the right tools and supplies. Here’s a list of what you’ll need for cleaning a cedar fence:
- A pressure washer (or a hose with a spray nozzle)
- A stiff-bristle brush or broom
- A mild cleaning solution or wood cleaner
- A bucket of water
- Protective gear (gloves, goggles, and a long-sleeved shirt)
- A wood stain or sealant (optional, for post-cleaning)
Step 2: How to Clean a Cedar Fence – The Right Way
Now that you have your tools ready, it’s time to start cleaning your cedar fence. Follow these steps to ensure the job is done properly:
1. Prepare the Area
Clear the area around your fence to avoid getting debris or cleaning solutions on your plants, garden, or outdoor furniture. Cover any plants that are close to the fence with plastic sheets or tarps to protect them from the cleaning solution.
2. Test a Small Area First
Before applying any cleaning solution or using a power washer, test the cleaning method on a small, hidden section of the fence to ensure it won’t damage the wood.
3. Use a Pressure Washer for Deep Cleaning
If your fence is particularly dirty or stained, using a pressure washer is one of the best ways to clean cedar wood fence efficiently. Power washing will remove dirt, grime, mold, and mildew that regular scrubbing cannot.
How to Power Wash a Cedar Fence:
- Set the pressure washer to a medium pressure setting (around 1500-2000 PSI) to prevent damaging the wood.
- Hold the pressure washer nozzle about 12 inches from the surface and spray in a sweeping motion. Start from the top and work your way down to prevent dirty water from dripping onto already cleaned areas.
- Move the nozzle in the direction of the wood grain to avoid gouging or splintering the wood.
This method is especially effective for cleaning cedar fence boards, as it removes buildup without harsh scrubbing.
4. Scrub Stubborn Areas
For stubborn stains or areas where the pressure washer didn’t reach, use a stiff-bristle brush to scrub the surface. Mix a solution of water and a mild wood cleaner, and apply it to the stained area. Use the brush to gently scrub the surface, removing the stains without damaging the wood.
Cedar Fence Cleaning Tips:
- For mold or mildew, add a small amount of bleach to the cleaning solution to kill the spores. Be sure to rinse the area thoroughly afterward.
- Avoid using harsh chemicals, as these can damage the wood and strip away its natural oils.
5. Rinse Thoroughly
After scrubbing, rinse the entire fence with clean water to remove any soap or cleaning residue. Let the fence dry completely before moving on to any additional treatments, such as sealing or staining.
Step 3: Brighten Cedar Fence – Bringing Back the Natural Shine
Over time, cedar wood can darken due to exposure to the sun and elements. If you want to restore its original, bright color, consider using a wood brightener after cleaning.
How to Brighten a Cedar Fence:
- Apply a Wood Brightener: After cleaning and rinsing your cedar fence, apply a wood brightener to bring back the vibrant, rich color of the wood. Wood brighteners contain oxalic acid, which helps to neutralize the effects of dirt, stains, and UV damage.
- Follow the Instructions: Wood brighteners are easy to apply with a sprayer or brush. Simply follow the instructions on the label, and allow the wood to dry before moving to the next step (if you plan to stain or seal).
This step will give your fence a fresh, natural appearance that enhances its beauty and durability.
Step 4: Cedar Fence Maintenance – Protecting Your Investment
After cleaning and brightening your cedar fence, it’s essential to maintain it to ensure it stays looking great for years to come. Regular maintenance helps prevent future damage and extends the life of your fence.
Cedar Fence Maintenance Tips:
- Staining and Sealing: After cleaning and brightening, it’s a good idea to apply a protective stain or sealant to your cedar fence. This will protect the wood from moisture, UV rays, and mold, while enhancing the natural color of the wood.
- Regular Cleaning: Clean your cedar fence at least once a year to remove dirt and prevent buildup of mold and mildew. If you live in a particularly damp or shaded area, you may need to clean it more often.
- Inspect for Damage: Regularly inspect your fence for signs of damage, such as broken boards, loose nails, or signs of rot. Prompt repairs will prevent more extensive damage in the future.
Step 5: Remove Stains from Cedar Fence – A Quick Fix
If you notice stubborn stains on your cedar fence, there are a few methods you can try to remove them.
Best Ways to Remove Stains from Cedar Fence:
- Vinegar Solution: Mix one part white vinegar with two parts water and apply it to the stain. Let it sit for 10-15 minutes before scrubbing with a brush and rinsing off.
- Oxalic Acid Solution: For more serious stains, such as tannin or rust stains, mix a solution of oxalic acid and water. This is especially effective for cedar fence restoration.

By following these cedar fence cleaning secrets, you can brighten your fence like a pro and maintain its beauty for years to come.
