How To Clean Exterior Wood

Keeping your exterior woodwork in top condition not only improves the look of your outdoor space but also protects your investment from the wear and tear of the elements. With regular cleaning and maintenance, you can preserve the natural beauty of your fences, sheds, and decking for years to come. This guide covers how to clean exterior wood with effective cleaning methods, seasonal challenges, and product recommendations from Rawlins Paints to help you maintain your outdoor timber.

 

 

Effective wood cleaning starts with preparation. Begin by brushing away loose debris such as leaves, dirt, and cobwebs. Pay close attention to any areas affected by mould or algae, as these may require targeted products.

Safety is paramount, so be sure to wear gloves and protective eyewear. Cover any nearby plants with a tarpaulin to prevent accidental contact with cleaning solutions.

When applying cleaning products, work with the grain of the wood to avoid damaging the surface. High-pressure washers may seem like a quick fix, but they can cause splintering and should generally be avoided unless specified as safe for wood.

 

 

Fences and sheds endure constant exposure to changing weather, often resulting in a grey, weathered appearance. To restore their original look, it’s important to choose the right products.

How to Clean a Fence or Shed: Step-by-Step Guide

1. Prepare the Wood: Begin by dampening the wood with water. This helps the cleaning product penetrate more effectively.
2. Apply the Cleaner: Use a brush to apply a generous layer of Mona-Clean Wood Replenisher, ensuring even coverage.
3. Let It Work: Allow the cleaner to sit for 15 to 20 minutes. This breaks down dirt and discolouration deep in the wood.
4. Scrub the Surface: Use a stiff-bristled brush to scrub away grime and loosen embedded particles.
5. Rinse Thoroughly: Rinse the wood with clean water to remove all product residues and dirt.
6. Dry Completely: Leave the wood to dry for 24 to 48 hours before applying any protective treatment.

Following these steps ensures your fence or shed is thoroughly cleaned and ready for further treatment.

 

 

Decking is particularly prone to wear due to foot traffic and exposure to rain and sun. Regular cleaning prevents slippery algae buildup and keeps the surface looking its best.

How to Revive Decking with Wood Reviver Power Gel

1. Sweep the Decking: Clear surface dirt by sweeping along the grain of the wood.
2. Apply Wood Reviver Power Gel: Spread the gel evenly along the grain and let it sit for 20 minutes.
3. Scrub Thoroughly: Use a deck brush to scrub the surface, removing dirt and stains.
4. Rinse with Water: Rinse the decking with plenty of water to wash away residue.
5. Allow to Dry: Let the decking dry completely, typically within 48 hours.
6. Protect with a Wood Oil or Stain: Apply a wood oil or wood stain to nourish and protect the decking.

This process restores your decking’s natural beauty while preparing it for long-lasting protection.

 

 

Each season presents unique challenges for your outdoor woodwork. Understanding these can help you take preventive action.

Spring and Summer

Increased sunlight can dry out wood, causing cracks and fading.

Solution: Apply a UV-resistant wood finish such as Decking Oil to protect the wood from sun damage.

Autumn and Winter

Persistent moisture can lead to mould and algae growth.

Solution: Use a product like this one from SmartSeal to remove algae and prevent future growth during damp months.

 

 

Regular upkeep is key to prolonging the life of your woodwork and keeping it looking fresh.

• Routine Cleaning: Sweep and rinse decking monthly during the warmer months to prevent dirt from settling. Clean fences and sheds annually.
• Reapplying Treatments: Refresh wood surfaces every 12 to 24 months with a protective oil or stain. For decking, consider using a non-slip treatment during the winter.
• Drainage and Protection: Ensure proper drainage around your woodwork to avoid water pooling at the base of fences and sheds. Adding protective furniture pads or mats can prevent scratches on your decking.
