How To Clean Decking Step-By-Step?

Step 1: Clear and prepare the area

Clear your deck’s surface. Take out any obstructions, large or small, from patio furniture to potted plants, and everything in-between.Next, take a broom to sweep the area. You should brush away leaves and dust, paying particular attention to places where debris could collect.

Step 2: Hose or pressure washer

To remove dirt and grime, use a garden hose or a pressure washer. To remove as much dirt and grime as possible, aim the sprayer at any heavily soiled areas.

Remember to take great care when using a pressure washer. If the pressure washer is used too close to the wood, it can cause damage that makes it difficult to clean up or treat. Use the lowest setting, and keep at least a few feet of distance between the sprayer and your deck’s surface.

After you have dealt with the problem areas, spray the remaining leaves, twigs, and grass between the decking boards.

Step 3: Scrub and rinse

Make a gentle cleaner with warm water and liquid soap to avoid damage to your decking. You can also use a wood deck cleaner.

Use a sponge or stiff-bristled brush to scrub the surface until the cleaning solution begins to lather. Allow the mixture to stand for five to ten minutes, or follow the directions on the deck cleaner label.

Finally, rinse the deck with clean water and allow it to dry.

Step 4: Treat mould and algae

The best way to clean decking from mould and algae is to use a ready-to-use concentrated disinfectant like Patio Magic. Ready to Use Spray This spray will not only remove stubborn stains but also prevents mold and algae regrowth from accumulating.

Spray the treatment on the affected areas, and allow it to dry. It’s easy to revive and maintain your deck without having to scrub or pressure wash it.

Step 5: Seal decking again

After giving your deck a thorough clean, it’s a good idea for you to seal it again. You may find that some sealers include mildew protection or a waterproofing agent. Make sure you explore all options to ensure you choose the right product for your deck.

To remove any dust or dirt that may have built up while the deck was drying, sweep it once again. Apply the sealer according the manufacturer’s instructions. Allow the sealant to dry completely before you move furniture or accessories back onto your deck.

Hello, I’m Pete and I’m currently based in the west of Scotland, in a small place called Rosneath, where I’m exploring my garden adventures. I personally started gardening around 6 years ago and initially, I started out by growing my favorite fruits and berries, such as strawberries, Raspberries & Gooseberries. Since then I’ve added a lot of vegetables and working closely with my neighbor, it’s been a lot of fun.
