Merbau Decking

Step 1: Sweep away the dirt and the leaves

  • Brush the deck down using a soft broom to remove the dirt / leaves. This will help to prevent some particles from building up and damaging your deck. If the deck needs a more thorough clean, you can use a stronger brush and some water.


Step 2: Use a high-pressure cleaner / Power wash

  • Using a high-pressure cleaner / power wash will wash away any remaining dirt and make sure you carefully go over the whole deck. If you are cleaning an older deck, make sure too that the high-pressure cleaner doesn’t split or crack the wood. For your safety wear closed shoes, safety glasses and earmuffs and if you don’t have a high-pressure cleaner, a simple hose will do too.


Step 3: Use a cleaner and mix it with water

  • Use a cleaner mixture for decks and mix it with water, make sure you follow the instructions to get the correct balance. Use a measuring cup too for accuracy and mix it with water thoroughly. Make sure you wear gloves, goggles and a mask when working this as its for your safety.


Step 4: Scrub the Deck

  • Dip your Deck Scrub Broom into the bucket of cleaning mixture and start scrubbing the deck. Thoroughly scrub every part of the deck to avoid some spotting. Leave the cleaning mixture on for 10-20 mins.


Step 5: Wash it a high-pressure clean

  • After you left the cleaning mixture for more than 20 mins, wash it down with the high-pressure / power wash hose. Make sure you wash away all the cleaning mixture along with any dirt and grime. Leave the deck to dry.


Step 6: You can now enjoy your clean deck

  • After cleaning your deck, now you have a brilliantly clean deck again, all you need to do is put your outdoor furniture or BBQ back where they were before. You can also stain or oil the timber to help protect it from the elements.

  • Shop around for a composite deck cleaner and make sure it specifies for composite decking and not for wood decking. You’ll want to do this first to make sure you have everything you need before you begin cleaning. Composite cleaners are best for regular composite boards. Read the instructions on your cleaner and determine a good day when it’s not too hot to focus on your deck. You’ll need to move furniture and cover any immovable fixtures with a trap.


Step 2: Remove Debris

  • Sweep the deck to remove the debris and dirt. Check in between the boards for little twigs and other debris that like to gather there.


Step 3: Power Wash your Deck

  • Power wash / use a high-pressure cleaner to wash your deck to remove any dirt, mildew or any other stains. If you have a newer deck, the manufacturer may recommend you to simply clean it with your garden hose. Mildew stained decks but will benefit from a heavier stream of water. Power washing can also reduce the amount of time.


Step 4: Apply Cleaner

  • Apply composite decking cleaner as per manufacturer’s instructions. Alternatively, use a mixture of dish soap and water. Scrub soiled areas with a cloth or soft-bristled brush. A stiff brush may scratch or dull the finish of your decking and should not be used.


Step 5: Spot Clean and Repair

  • Don’t let the stains to pile up. Clean spills ASAP so they don’t get worse over time. Regularly sweeping your deck can help protect it from mold and keep debris to a minimum. While cleaning, look for any nails or screws that need to be secured or other issues that requires attention. Cut back foliage that is hanging over your deck to reduce debris and diminish the chance of mold growth.
