A cedar deck can be a beautiful and durable addition to your home, but like any outdoor feature, it requires regular maintenance to preserve its appearance and longevity. Over time, dirt, debris, and mildew can accumulate, dulling the natural beauty of the wood. Proper cleaning not only restores the cedar’s vibrant color but also helps prevent damage and extends the life of the deck.

This guide on how to clean a cedar deck will walk you through the essential steps to clean your cedar deck effectively and safely.

What is Cedar?

Cedar is a type of softwood that is commonly used for outdoor projects, such as decks and fencing. It has natural oils and tannins that make it resistant to rot, decay, and insects, making it an ideal choice for exterior use.

However, despite its durability, cedar still requires some maintenance to keep it looking its best.

Why Clean a Cedar Deck?

Over time, dirt, grime, and mold can accumulate on your cedar deck, causing it to look dull and dirty. This not only affects the appearance of your deck but also its longevity. If left untreated, these contaminants can cause the wood to deteriorate and potentially lead to expensive repairs or even replacement.

Regularly cleaning your cedar deck will not only keep it looking beautiful but also extend its lifespan by removing these harmful substances.

Tools and Materials Needed

• Soft-bristle Deck Brush
• Garden Hose or Pressure Washer (Low Pressure Only)
• Bucket
• Oxygen Bleach or a Specialized Cedar Deck Cleaner
• Mild Detergent (Optional)
• Broom or Leaf Blower
• Rubber Gloves and Safety Glasses
• Scraper (for Stuck-on Debris)

9 Simple Step-by-step Guidelines on How to Clean a Cedar Deck

Step 1: Clear the Deck 

Begin by removing all furniture, planters, and decorative items from the deck. This will ensure you have full access to the surface for thorough cleaning.

Use a broom or leaf blower to sweep away loose debris, such as leaves, dirt, or small branches, that may have accumulated. Clearing the deck entirely helps prevent obstacles during the cleaning process and ensures that every corner of your cedar deck can be properly addressed.

Step 2: Sweep or Blow off Debris 

With the deck cleared, it’s time to ensure the surface is free of any remaining loose dirt or debris. Use a stiff-bristle broom to thoroughly sweep the deck, paying close attention to the spaces between boards where dirt can accumulate.

Alternatively, a leaf blower can be used for a quicker cleanup, especially for hard-to-reach areas. Taking this step will help prepare the deck for deeper cleaning by ensuring no loose material interferes with the process.

Step 3: Prepare Your Cleaning Solution

Mix oxygen bleach or specialized cedar deck cleaner with water according to the manufacturer’s instructions in a bucket.

If using oxygen bleach, add mild detergent for better results. Avoid using chlorine bleach as it can damage the wood fibers and cause discoloration.

Step 4: Apply the Cleaning Solution

Using a broom or a brush with soft to medium bristles, generously apply the cleaning solution to the deck surface. Work in small sections to ensure even coverage and avoid letting the solution dry on the wood before scrubbing.

Focus on areas with visible stains, dirt, or mildew, scrubbing gently to loosen debris without damaging the wood. Allow the solution to sit for about 10-15 minutes, giving it time to deeply penetrate and lift any buildup.

Step 5: Rinse Thoroughly 

After the cleaning solution has had time to work, use a garden hose or pressure washer to thoroughly rinse the deck. Start at one end and work systematically to ensure all residue is removed.

Pay extra attention to corners, seams, and other areas where dirt or cleaning solution might accumulate. If using a pressure washer, set it to a low-pressure setting to avoid damaging the wood. Make sure the deck is completely free of soap and debris before allowing it to dry.

Step 6: Let Dry 

Once the deck has been thoroughly rinsed, allow it to dry completely before proceeding to the next steps, such as staining or sealing. Drying times may vary depending on the weather, but it’s generally best to wait at least 24 to 48 hours.

Ensure the deck is in a well-ventilated area with plenty of sunlight, as this promotes faster and more even drying. Check for any remaining moisture by touching the surface before moving forward to avoid trapping water under sealants or finishes.

Step 7: Sand (If Needed)

Before applying any stains or sealants, inspect the deck for any rough or splintered areas that may require sanding. This step is especially important if the wood feels uneven or if the previous finish has not fully worn away. Use a medium-grit sandpaper (around 80-100 grit) for smoothing out surfaces and edges.

Sanding helps the wood better absorb the stain or sealant, ensuring a more uniform and long-lasting finish. After sanding, be sure to clean the deck thoroughly again to remove all dust and debris before proceeding to the next step.

Step 8: Apply Sealant or Stain

Now that your deck is clean and dry, it’s time to protect it from future damage by applying a sealant or stain.

Choose a product specifically designed for outdoor use and follow the instructions carefully. Generally, you will need to apply multiple coats and allow for proper drying time in between.

Step 9: Regular Maintenance

To keep your deck looking great, it’s important to regularly maintain it. This includes sweeping off debris, inspecting for any potential damage or rot, and reapplying sealant or stain as needed. It’s also a good idea to periodically pressure wash your deck to remove built-up dirt and grime.

Following these steps on how to clean a cedar deck will help keep your outdoor space looking beautiful and extend its lifespan. With proper care and maintenance, you can enjoy your cedar deck for years to come!

Do You Need to Hire Professionals?

While maintaining a cedar deck is something many homeowners can handle on their own, there may be times when hiring professionals is the best choice. If your deck has significant damage, such as deep cracks, extensive rot, or needs structural repairs, professional expertise can ensure the work is done correctly and safely.

Additionally, professionals have access to specialized tools and products that can provide a deeper clean or a more durable finish. For those with limited time or little experience in deck maintenance, hiring experts can save both effort and the potential cost of mistakes. Ultimately, whether or not to hire professionals depends on the scale of the project and your comfort level with tackling the job yourself.

How Much Will It Cost?

The cost of deck maintenance or repairs can vary widely depending on several factors, such as the size of the deck, the extent of the work needed, and the materials involved. For basic cleaning and sealing, homeowners can expect to pay anywhere from $1 to $3 per square foot if hiring a professional.

For more extensive repairs, such as replacing damaged boards or structural components, costs can range from $200 to $500 or more, depending on the complexity of the job. If you choose to handle the maintenance yourself, you will need to consider the price of cleaning solutions, sealants, and any required tools, which can range between $50 and $150 for smaller projects. It’s always a good idea to obtain multiple quotes from professionals to ensure you’re getting a fair price that fits your budget.

Frequently Asked Questions

Q: Can I Use a Pressure Washer on My Cedar Deck?

A: Yes, you can use a pressure washer to clean your cedar deck. However, it’s important to use the appropriate setting and technique to prevent damaging the wood. Start with a low-pressure setting and gradually increase as needed. Additionally, make sure to keep the nozzle moving at all times and avoid holding it too close to the wood.

Q: How Often Do I Need to Seal or Stain My Cedar Deck?

A: This will depend on factors such as sun exposure, weather conditions, and foot traffic. As a general rule of thumb, it’s recommended to reapply sealant or stain every 2-3 years. However, if you notice the finish starting to fade or wear off, it’s best to reapply sooner rather than later.
