Why Regular Deck Cleaning Is a Must
Wooden decking adds style and function to your outdoor space, but the unpredictable British weather brings plenty of challenges. Rain, frost, algae, mud, and even barbecue grease can leave your decking looking tired—or worse, slippery and unsafe.
Routine cleaning helps maintain both the beauty and safety of your deck, and it doesn’t require harsh chemicals. With the right method and products, like Bio-D’s Home and Garden Cleaner or Multi Surface Cleaner, you can tackle grime, protect the wood, and keep your garden eco-conscious.
This guide shows you exactly how to clean decking boards for lasting results.
Understand Your Deck: Know the Material
Before cleaning, identify your decking type. Different materials need different care.
Softwood (e.g., Pine, Spruce)
Hardwood (e.g., Oak, Iroko, Teak)
Composite Decking
Both Bio-D Home and Garden Cleaner and Multi Surface Cleaner are suitable for these surfaces and offer safe, biodegradable formulas that won’t harm your deck, or the planet.
Step-by-Step: How to Clean Decking Boards
Move furniture, pots, and decorations. Sweep loose leaves and debris using a stiff broom.
Dry brush the surface to dislodge stuck-on dirt, paying attention to corners and joins. While doing this, check for loose boards or screws and repair as needed.
Both Bio-D Home and Garden Cleaner and Multi Surface Cleaner are:
What’s the difference?
Pro tip: For large decking areas, dilute the Home and Garden Cleaner into a watering can or garden sprayer for easy coverage.
Apply the diluted cleaner using a long-handled brush or decking broom. Work in sections, scrubbing along the grain to avoid damaging the wood fibres.
Pay special attention to:
Let the cleaner sit for a few minutes, then rinse thoroughly with a hose or buckets of clean water.
Treating Common Deck Issues
Algae, Moss, and Mould
Pour Bio-D Home and Garden Cleaner directly onto green areas and allow it to work for 10–15 minutes before scrubbing. Repeat as needed for heavy build-up.
Grease and Food Stains
Use a concentrated mix of Home and Garden Cleaner or Multi Surface Cleaner in a reusable spray bottle. Apply, let sit, scrub gently, and rinse.
Black Mould or Mildew
These thrive in moisture-rich corners. Apply the sanitiser, scrub with a soft-bristled brush, and rinse well.
Greying Wood
Natural UV exposure turns wood grey. Cleaning helps, but to restore colour, consider applying a suitable deck oil after cleaning and drying.
Can You Pressure Wash Decking?
Yes, with caution. Pressure washing can be effective but may also damage wood if misused.
Follow up with a Bio-D cleaner to remove embedded dirt and bacteria for a deeper clean.
Post-Clean Protection
After cleaning and fully drying your deck, consider applying a wood preservative or oil (suitable for your deck type). This seals the surface, enhances appearance, and prevents water absorption.
Only apply treatments in dry weather and ensure the deck is moisture-free.
