Deck cleaning tips and tricks for summer

As we welcome the warmer months, our outdoor spaces once again become the heart of family gatherings and entertaining friends. Your deck is an extension of your home, offering a perfect spot for summer barbecues, evening soirees, or just a quiet afternoon with a book. A clean, well-maintained deck not only enhances your home’s appearance but also creates an inviting space for relaxation and entertainment. Learn how you can protect and preserve the longevity of your deck with these practical and essential deck maintenance and cleaning tips.

Why clean your deck?

A pristine deck isn’t just about curb appeal. Regular cleaning wards off rot, mold, and mildew, preventing potentially hazardous slips and extending your deck’s life. Maintaining a beautiful deck also reinforces the overall value of your home, showcasing a well-cared-for exterior.

Prepare your deck for cleaning

Before diving into the cleaning process, proper preparation is key:

1. Remove all furniture, potted plants, and decorations from your deck.
2. Sweep the deck thoroughly to remove loose dirt, leaves, and debris.
3. Cover nearby plants and outdoor fixtures to protect them from deck cleaning solutions.
4. Inspect the deck to identify any areas that may require repair.

Cleaning tips for all deck types

Decks are prone to stains from mold, mildew, and spilled substances. The below is a guide which can be followed and applied for cleaning all deck types:

1. Snow and ice: Always remove snow and ice with a plastic shovel. Avoid using metal-tipped shovels as they can damage your deck’s surface. To prevent ice patches, use calcium-chloride based products over sand to prevent surface damage. 
2. Mold and mildew: Use a white vinegar solution (1 part vinegar to 3 parts water). Apply with a brush and rinse thoroughly. Not only is this cleaning method safe for all deck types but it is also an eco-friendly option.
3. Food stains: Use a paste of baking soda and water. Apply the paste, let it sit for a few minutes, and then scrub and rinse. 
4. Oil and grease: Use dish soap, such as blue Dawn, and warm water. Apply the mixture, scrub and rinse thoroughly. 

Choosing the right maintenance method 

When it comes to your deck, gentle care is paramount. While power washing can be effective, it’s crucial to use a lower pressure setting to avoid damaging wood fibers. For more delicate tasks, a simple hand scrub with a soft-bristled brush can be just as effective, lifting dirt without harming the surface beneath. Selecting a suitable cleaner relies on the type of material your deck is made of. Natural solutions like vinegar and water can work wonders for wood decks, while special composite deck cleaners are recommended for synthetic alternatives.

How to care for a wood deck

Traditional wood decks are most common among homeowners and are known for their natural beauty. Additionally, wood decks are a more affordable option as compared to alternative options like composite decking. However, they do require more ongoing maintenance and specialized care.

• Wood types: Natural wood types, such as cedar or redwood, are naturally more resistant to decay, insects and the weather as compared to pressure-treated wood. However, they require sealing and staining to maintain and preserve the longevity of the wood. While pressure-treated wood is treated with chemicals to prevent rot and decay, they are prone to warping and cracking if regular maintenance is not applied.
• Sealing and staining: For natural wood decks, a sealant should be reapplied every 1-2 years to protect the wood from moisture, UV rays, and wear. Whereas, repainting and restaining can be done every 1-3 years, depending on how much the color has faded or been damaged. Choose a product suitable for your deck’s wood type and follow the application instructions carefully.
• Garden hose or power washing: Generally, for most light cleaning and spills, a garden hose with a spray nozzle can effectively rinse away dirt and grime. Start from one end of the deck and work your way across, ensuring even coverage. For a deeper clean or to prepare for restaining or resealing, a power washer is ideal. Use a spray fan setting and keep the nozzle as least 12 inches away from the surface to avoid damaging the wood. Move the washer in a consistent, sweeping motion. Always start in a small, inconspicuous area first to ensure the proper pressure and distance to avoid surface damage.

Sealing and protecting your wood deck

Cleaning should always be followed by sealing, which guards against moisture and sun damage. Choose a sealant compatible with your deck material and apply during a dry, mild day for best results. This practice significantly contributes to your deck’s longevity and beauty.

1. Apply a water-repellent sealer to guard against moisture damage.
2. Repair any damaged boards or loose railings.
3. Establish a regular sweeping and spot-cleaning routine to prevent staining.
4. Place deck mats in high-traffic areas to catch dirt and debris.
5. Trim overhanging plants to reduce leaf litter and excess shade (which promotes mold growth).
6. Consider periodic professional checks to ensure safety and avoid larger hazards.

How to care for a composite deck

Composite decks have grown in popularity because of their durability, variety of color and textures, and low care maintenance. In most cases, cleaning your composite deck with warm soapy water will suffice. However, proper cleaning and preventative maintenance will go a long way in preserving your investment, ensuring you have a long-lasting and beautiful deck. 

• Composite deck cleaner: Many manufacturers produce cleaners specifically designed for composite decking. These are typically the safest and most effective option.
• Commercial deck brighteners: These can help restore the color of faded composite decking. Always check your deck manufacturer’s recommendations, as some brighteners may not be suitable for certain types of composite decking.
• Avoid harsh chemicals: Don’t use chlorine bleach, as it can damage the composite material and even void your manufacturer’s warranty.
• Don’t: Use stiff or abrasive cleaning brushes as it could scratch your deck’s surface. When in doubt, follow your manufacturer’s specific instructions.
• Don’t: Clean in direct sunlight, as the heat may cause the surface to dry before the cleaner can be properly rinsed. Additionally, don’t let the cleaner dry on the surface as it may create a white film which can be difficult to clean and lead to premature surface damage.

Before using any deck cleaning solution, either natural or commercial grade cleaner, always confirm which solution is suitable and safe for your deck materials. Also, consider which solutions are safe for use around children, pets and plants. Be sure to thoroughly rinse your deck with clean water and allow it to dry completely before replacing furniture. Preventing stains is equally critical; immediate clean-up and regular care can keep them at bay.

Professional deck cleaning services

For large decks, severe stains, or annual deep cleaning, hiring a professional service can be beneficial. Professionals have the expertise and equipment to handle tough cleaning jobs efficiently. Look for a reputable deck cleaning service with positive reviews and reasonable pricing. Ensure they use safe and effective cleaning methods for your specific deck material.

A clean, well-maintained deck is the cornerstone of a summer-ready outdoor space. By following these tips and tricks, you can maintain a pristine deck all season long. Remember, consistent care not only enhances your deck’s appearance but also extends its lifespan, protecting your investment for years to come. Whether you choose to tackle the cleaning yourself or hire a professional, the results will be well worth the effort.
