Regular cleaning is essential for upkeep and deck maintenance, but knowing how to safely clean a deck for long-lasting results can vary depending on the materials used. Regular cleaning and maintenance ensures your deck looks its best year-round and enhances safety and longevity. Whether you have a wood, vinyl, PVC, or composite deck, using the correct cleaning techniques and tools can prevent damage and keep your deck in optimum condition.
In this blog, we’ll provide techniques and tips for how to safely clean a deck based on the type of deck material used. In addition, we also offer recommended guidelines on how to safely power wash your deck to mitigate damage to your deck surface.
Signs Your Deck Needs To Be Cleaned
You’ll know it’s time to clean your deck when you start noticing visible signs like dirt buildup, discoloration, or the appearance of mold and mildew, especially in shaded areas. If the deck becomes slippery when wet, that’s a key indicator of algae growth, which can pose a safety hazard. Additionally, if your deck feels rough to the touch or shows signs of staining from food, drink, or environmental debris like leaves, it’s a good time to schedule a cleaning. Regular maintenance is recommended at least twice a year, typically in the spring and fall, to prevent long-term damage.
How to Safely Clean Different Deck Materials for Long-Lasting Results
Each deck material has its own cleaning needs, and understanding how to care for your deck will help you avoid unnecessary damage. Here’s a breakdown of how to clean each type:
1. How to Safely Clean A Wood Deck
Wood decks are classic and beautiful but require consistent maintenance to avoid problems like mildew, rot, and fading.
Cleaning Process:
- Sweep the deck to remove dirt and debris.
- Mix a gentle wood cleaner with water or a DIY mixture of soap and warm water.
- Scrub with a stiff-bristle brush to remove stains, mould, or mildew.
- Rinse with a garden hose, avoiding harsh chemicals that may damage the wood fibres.
Pro Tip:
- Consider using a wood deck brightener to restore the wood's natural colour. Additionally, remember to seal or stain your wood deck every 1-2 years to protect it from weather damage.
2. How to Safely Clean a Vinyl Deck:
Vinyl decks are known for their durability and ease of maintenance, but they can become stained or develop mould over time.
Cleaning Process:
- Start by sweeping away loose debris.
- Use a mild detergent mixed with water to scrub the surface.
- Apply a soft-bristle brush for stubborn spots.
- Rinse thoroughly with a hose to remove soap residue.
Pro-Tip:
- To prevent long-term discolouration, clean your vinyl deck using a mild detergent, especially after storms or when exposed to tree sap or bird droppings. Avoid using bleach, harsh chemicals and abrasive tools, as they can weaken the vinyl over time.
3. How to Safely Clean a PVC Deck
PVC decks are another low-maintenance option, but they still need occasional cleaning to remove dirt and grime.
Cleaning Process:
- Sweep the deck to remove dirt.
- Use a specialized PVC deck cleaner or water and mild soap mixture.
- Scrub the deck using a soft-bristle brush or cloth.
- Rinse the surface thoroughly with water to avoid any soap buildup.
Pro-Tip:
- PVC decks are highly resistant to mould and mildew, but regular cleaning will maintain a cleaner appearance. For tough stains, use a non-abrasive cleaner and soft cloth to avoid scratching the PVC surface, and be sure to rinse thoroughly to prevent residue buildup.
4. How to Safely Clean a Composite Deck
Composite decks are durable and weather-resistant but require proper care to prevent staining and mould growth.
Cleaning Process:
- Sweep the deck to remove leaves and debris.
- Use a composite deck cleaner or a mixture of soap and warm water.
- Apply the cleaner with a soft brush and scrub gently.
- Rinse the surface thoroughly to ensure no cleaner is left behind, which can cause streaking.
Pro-Tip:
- For decks made from composite material, use a specialized composite deck cleaner that breaks down stains and prevents mould. Avoid metal shovels or sharp tools when removing debris to prevent scratches on the surface.
How to Safely Power Wash Your Deck
Power washing is an effective way to clean your deck, but it is also important to consider the material you’re working with to avoid damaging your deck.
Wood Decks
- Pressure setting: Use a lower setting, around 500-600 psi, to avoid gouging the wood.
- Keep the nozzle moving and avoid staying in one spot too long.
Vinyl Decks
- Pressure setting: Set the power washer to around 1,300-1,500 psi.
- Hold the nozzle at least 12 inches from the surface to prevent damage to the vinyl.
PVC Decks
- Pressure setting: Similar to vinyl, set the pressure to 1,300-1,500 psi.
- Hold the nozzle a safe distance away to avoid scratches.
Composite Decks
- Pressure setting: Keep the pressure around 1,000-1,200 psi.
- Use a fan tip nozzle and maintain a distance of about 8-12 inches from the surface.
While power washing is an effective way to clean your deck, always follow manufacturer guidelines and avoid excessive pressure to prevent damage to the deck surface.
