How to clean decking boards effectively

Step 1: Clear the deck

Before you start cleaning, you should remove all furniture, potted plants and other items from your deck. This step will ensure that you have a clear surface to work on and that you don’t accidentally damage any of your belongings.

Step 2: Sweep the deck

Use a stiff-bristled broom or a leaf blower to remove any debris, such as leaves, dirt, and twigs from the deck surface. You want to remove as much debris as possible to prevent it from getting ground into the deck during the cleaning process.

Step 3: Apply deck cleaner

Apply a deck cleaner to the entire surface of your deck. There are many types of deck cleaners available, so be sure to choose one that is compatible with your decking material – timber, composite and so on.

Read and follow the manufacturer’s instructions carefully. Some cleaners may require you to wet the deck first, while others may need to be applied to a dry surface.

Step 4: Scrub the deck

Once you’ve applied the deck cleaner, use a stiff-bristled brush to scrub the surface of the deck thoroughly. Pay special attention to areas with stains or dirt build-up. You may need to use a smaller brush or toothbrush to clean hard-to-reach areas, such as between deck boards.

Step 5: Rinse the deck

After scrubbing, rinse the deck thoroughly with a garden hose. Make sure to remove all of the deck cleaner and any dirt or debris that has been loosened. Rinse from the highest point to the lowest to prevent streaks.

Step 6: Let the deck dry

Allow the deck to dry completely before replacing furniture or walking on it. Depending on the weather, this may take a few hours to a full day.

Step 7: Apply a sealant (optional)

For best results, apply a sealant to the deck after it’s completely dry. A sealant will help to protect the wood from moisture and harmful UV rays, preventing it from warping or fading over time. Be sure to choose a sealant that is compatible with your decking material.


Final thoughts

Regular cleaning is essential to keep your decking in good condition.

And now that you know how to clean decking without damaging it, you’re all set to enjoy those lazy, long British summer evenings in style with friends and family for many years to come.
