Low-maintenance decks have become a popular choice for homeowners who want the beauty of an outdoor living space without the hassle of constant upkeep. Composite, PVC, and aluminum decks are durable, resist mold and mildew, and don’t require sanding, staining, or sealing like traditional wood decks. However, even low-maintenance decks need a little care to keep them looking their best. Regular cleaning helps prevent dirt buildup, removes stains, and prolongs the life of your deck.
In this blog post, we’ll walk you through how to clean a low-maintenance deck, with simple steps to keep it fresh and looking new for years to come.
Why Clean a Low-Maintenance Deck?
Even though low-maintenance decking is designed to resist stains and weathering, regular cleaning is still important to remove dirt, pollen, debris, and occasional spills. Over time, even the most resilient materials can accumulate grime or stains from food, outdoor elements, or mildew. Proper care ensures:
- Longevity: A clean deck lasts longer and maintains its appearance.
- Safety: Regular cleaning prevents slips and falls caused by wet leaves, algae, or dirt.
- Aesthetic Appeal: Keeping your deck clean enhances its appearance, ensuring it remains an inviting space for relaxation and entertainment.
Materials You’ll Need:
- Mild soap or dish detergent
- Soft-bristle brush or broom
- Garden hose or pressure washer (with a gentle setting)
- Bucket of warm water
- Soft cloth or sponge
- Specialized composite deck cleaner (optional, for tough stains)
- Non-abrasive cleaning pad
Steps to Cleaning a Low-Maintenance Deck
1. Clear the Deck
Start by removing all furniture, planters, and other items from your deck. This will give you a clear surface to work on and prevent obstacles while cleaning. Don’t forget to sweep the deck thoroughly, removing leaves, dirt, and debris that may have collected between the boards or in the corners.
2. Rinse with Water
Using a garden hose, gently rinse the deck to remove loose dirt, pollen, or dust. For a quicker clean, you can use a pressure washer, but make sure it’s on a low setting (below 1,500 PSI) to avoid damaging the decking material. Keep the nozzle at least 8-12 inches away from the surface to prevent accidental gouging or scratches.
Tip: If you’re using a pressure washer, avoid using it near the railing or at joints to prevent water from seeping into any gaps, which could cause long-term damage.
3. Prepare a Cleaning Solution
Mix a solution of warm water and a mild dish detergent in a bucket. If you have a composite deck, avoid harsh chemicals like chlorine bleach, which can damage the decking material over time. Many deck manufacturers also offer specialized composite deck cleaners designed to safely clean the surface without harming the material.
If you’re dealing with a tougher stain (such as from grease, wine, or berries), look for cleaners specifically formulated to tackle these stains without damaging the deck’s finish.
4. Scrub the Deck Gently
Dip a soft-bristle brush or broom into the soapy water and gently scrub the deck boards. Work in sections, scrubbing along the grain of the material to avoid scratching or damaging the surface. Focus on areas with more dirt buildup or visible stains, giving extra attention to high-traffic areas, corners, and grooves.
For stubborn spots, use a non-abrasive cleaning pad to scrub without scratching the surface.
Tip: Be mindful not to use wire brushes or steel wool on composite or PVC decks, as these can damage the surface or leave behind permanent marks.
5. Rinse Thoroughly
Once you’ve scrubbed the entire deck, rinse it thoroughly with clean water from your garden hose. Make sure all the soap and debris are completely washed away to avoid any residue or slippery surfaces when the deck dries.
6. Dry the Deck
Allow the deck to air dry completely before replacing furniture or walking on it. Drying time will depend on the weather, but it typically takes a few hours in warm, sunny conditions. Avoid putting furniture back on a wet deck to prevent stains or watermarks from forming.
7. Address Stains (Optional)
If certain areas of the deck still have stains, you may need to treat them with a specialized deck cleaner. Look for a product designed for your specific decking material and follow the manufacturer’s instructions. Most composite or PVC deck cleaners are effective at removing tough stains like grease, oil, or food spills.
For oil or grease stains, applying the cleaner as soon as possible is crucial. The longer the stain sits, the more difficult it may be to remove.
Routine Maintenance Tips for Low-Maintenance Decks
1. Regular Sweeping: Sweep your deck regularly to keep leaves, dirt, and debris from collecting in corners or between boards. This helps prevent mold and mildew buildup, especially after rain.
2. Rinse After Heavy Rain: After storms or heavy rain, rinse your deck to remove any debris, mud, or dirt that may have splashed up. This is particularly important in areas where leaves and dirt accumulate.
3. Protect from Furniture Scratches: Use furniture pads or glides on chair and table legs to prevent scratches on your deck’s surface.
4. Trim Nearby Plants: Trim back any plants or trees that hang over your deck. Overhanging branches can drop leaves, sap, and other debris onto your deck, which can lead to staining or encourage mold growth.
5. Avoid Harsh Chemicals: Stick to mild soaps and deck cleaners recommended by the manufacturer. Harsh chemicals can damage the finish of composite, PVC, or aluminum decks and void warranties.
6. Seasonal Deep Cleaning: Even if your deck doesn’t appear dirty, performing a deep cleaning at least twice a year, especially in spring and fall, will help maintain its appearance and longevity.
Conclusion
Low-maintenance decks are designed to provide beauty and function without the heavy upkeep required by traditional wood decking. However, a little regular care goes a long way in preserving your deck’s appearance and ensuring it lasts for many years. By following these easy steps and incorporating simple maintenance habits, you can keep your deck looking fresh, clean, and ready for outdoor entertaining all year round.
