How To Clean Garden Decking Effectively

Whether your deck is looking a bit worse for wear or you simply want to spruce up your patio for summer, we’ve got you covered! Our handy guide will show you how to clean garden decking effectively in a few easy steps.

When to clean your decking

Since your deck is exposed to the elements year-round, regular maintenance is key to its longevity. If you want to keep your decking in tip-top shape, give it a thorough cleaning at least once per year.

An annual wash can breathe new life into your deck, preserve the integrity of the wood, and ultimately help to prevent costly repairs.

How to clean wooden decking in five simple steps

Step 1: Clear and prepare the decking area

Start by clearing everything from the surface of your deck. Remove anything that might get in your way – from large patio furniture to small potted plants and everything in between

Next, grab a broom and give the entire area a thorough sweep. Brush away dust and leaves, and pay particular attention to any nooks and crannies where debris can collect.

Step 2: Spray decking with a pressure washer or hose

Use a pressure washer or garden hose to loosen and rinse away any dirt or grime from your garden decking. Aim the sprayer directly at heavily soiled spots to remove as much debris as possible.

Just remember: if you’re using a pressure washer, this step needs to be done with great care. A pressure washer can quickly damage the wood if used too closely, making it even harder to clean or treat. Choose the lowest setting and leave at least a few feet between the spray nozzle and the surface of your deck.

Once you’ve addressed the most problematic areas, be sure to spray in between the decking boards to rinse away any remaining twigs, leaves or grass.

Step 3: Scrub and rinse decking

To clean the deck, make up a gentle cleaning solution with warm water and liquid dish soap. Alternatively, you can use a speciality wood deck cleaner.

Saturate the surface and scrub the deck with a stiff-bristled brush or sponge until the cleaning solution starts to lather. Let mixture stand for 5 to 10 minutes (or follow the instructions on the deck cleaner label).

Lastly, rinse with clean water and leave the deck to dry.
