Composite decking is a low maintenance material for building your deck, but it still requires some maintenance. As a matter of fact, a little maintenance goes a long way to help your composite boards last longer and prevent any damage that may happen. Most composite decking boards come with a warranty, so proper maintenance and cleaning procedures are necessary for those just-in-case scenarios where you might have to use the warranty.

It is always a good idea to double-check the cleaning instructions for your brand of composite decking boards before cleaning so you don’t do anything that will void the warranty. If you have a composite deck installed in your home or commercial property, a simple soapy water solution with a pressure cleaner should do the trick. However, some composite decking comes with cleaning guidelines and require more effort to maintain than others.

A few factors will dictate how often you need to clean and what type of cleaning is required: the season and location, along with how much traffic the deck gets and if debris tends to accumulate on it.

Preventative cleaning is definitely a better option than reactive cleaning to undo the damage if you want your deck in top shape.

Keep a simple cleaning routine

Most composite board manufacturers suggest a weekly or monthly cleaning to keep the deck as clean as possible. This can be as simple as a quick once-over with a broom to clean off dirt, leaves, and other accumulated materials.

For larger decks or in autumn, when there may be a large amount of leaves that need to be removed and cleared, you may find using a leaf blower easier. For decks with a lot of dirt accumulation, use a high pressure water cleaner to hose the dirt off.

Remove stubborn dirt from your composite decking

For hard to remove dirt, you’ll want to use soapy water and a brush. Start by hosing off the deck and then use a soft bristle brush with a mild detergent mixed with water to scrub the deck. Make sure that you get into the cracks and corners of the deck, this will ensure that you will remove any mildew or mould that could possibly build up on the deck.

A wash with soapy water is recommended at least twice a year, and more often if exposed to a very dusty or humid and moist environment. Or you decking material is a 1st generation or un-capped composite.

If your deck is larger or if scrubbing it seems too hard, you can use a pressure washer instead. Make sure it is set to under 3100 psi and the nozzle is at least 21 cm from the boards. To prevent damage always spray with the grain of the composite.

For both scrubbing and pressure washing, make sure to completely rinse the deck with clean, preferably warm, water afterwards. Soap can leave a film on composite decking that could damage it over time. Also, never use a harsh detergent or acetone solution; instead opt for mild soap and use a high-water dilution ratio.

Take fast action with any food spills

On a day-to-day basis, especially during the summer when outdoor entertaining is frequent, make sure you remove and clean any food spills as soon as possible. Certain composite board manufacturers have a material warranty that will be voided if food is left sitting longer than seven days.

Remove the food or drink spill and then wash using a warm soapy water mixture. This method is not limited to food alone, it will also work on any grease or oil stain.

Keep your deck in pristine condition

Some composite board manufacturers will have brand specific ‘brighteners’ that can be used after cleaning to protect the boards and will also remove any tannins that could be left over from debris. Double check to verify the brightener can be used with the decking material you have, clean the deck, then apply the product after the deck is completely dry. For 1 generation or un-capped decking there are stains or sealers similar what is used on timber decking to restore and revitalise your deck.

All in all, cleaning a composite deck is quite simple. With regularly scheduled maintenance, your deck will look great and last a whole lot longer.

The installation team were top notch and very professional, but the supply people at the warehouse said stock was there, then not, so we chose another board, then it turned out they did have stock. Overall a good experience.

The guys at Decking Perth were fabulous to deal with. Being a DYI project and never having built a deck before I had many questions which they were happy to answer. Their choice of products was extensive and we ended up choosing the Moisture Shield range. The product was great to work with and the result was fantastic. Decking Perth helped with all the ordering and delivery and happily accepted any returned unused items that were not required.Fantastic experience all round and we love our new deck.Thanks guys.

After visiting several decking businesses, I landed here to find excellent service, listening skills and advice. After choosing the material, they provided several quality different people to quote the job........(how much time did that save!) and as a result I have a lovely front and back deck. so pleased.

very good experience, very knowledgeable staff and high level of customer service.
Adrian at Decking Perth was very knowledgable and helpful and provided sound advice about suitable materials and finishes for my courtyard decking project for which I was very grateful. A big thanks also to Blake (contractor referred by Adrian) who did such a wonderful job translating my ideas into reality (including the bench seating) and whose workmanship was excellent. I am so happy with the finished Jarrah deck, which looks better than I could have hoped, and with my experience dealing with Adrian and Blake. Thanks so much guys!

We contacted Decking Perth via a website contact form and received a call back within an hour! We visited the showroom on a Saturday, took colour samples home and were contacted by two carpenters on the following Monday morning. Both were prompt and very reasonably priced. Our decking was completed within a day and all offcuts and rubbish removed.We are thrilled with the results.The process was quick, efficient, friendly and well priced.Thank you. :)

The level of service, quality of the timber and professionalism of the Decking Perth Team is without question the Best in the West!

This week I have taken delivery of some additional subframe H3 and Merbau 5.7 FJ decking and was not let down. The only place I will order my decking supplies in future.
I went to a few places but none were as helpful as these guys,Got everything I needed with their help including some helpful advise on installation. Best I found and reasonably priced!Much appreciated to all

We couldn't be more pleased with the result of our new decking built by Dean and his team from Allstyle Build using composite decking sourced from Decking Perth. Dean's customer service and attention to detail was really appreciated and his pricing was value for money given the excellent result. Wouldn't hesitate recommending both Allstyle Build and Decking Perth's products for any decking project.

I had no idea where to start when it came to getting decking installed. I was so pleased when I found Decking Perth because they did all the tricky stuff for me - all I had to do was tell them what I was after and what colour and they did the rest. The contractor I ended up choosing to do the instal was fantastic. Couldn't be happier with my new deck! So thank you!

Decking Perth provide great advice for novice deck buyers by showing you a wide range of products underpinned by knowledge and a conduit to deck builders. A couple of days after we visited Decking Perth one of their preferred contractors provided a very competitive quotation and we engaged AllStyle Carpentry. Decking Perth supplied all materials as they are a One Stop Shop for the contractor. The Modwood Xtteme deck looks fantastic and we could not be happier with it. Thank you Decking Perth as your business supported our thinking and your advice saw the planning come together and we now have a lovely deck.Phill Cribb

I contacted Decking Perth regarding an extension to our current Trex Deck. They took my details and within 4 hours I had been contacted by 2 decking installers and both had attended and quoted within 3 days. Jamie from Elite Decking had the job completed the following week! Lovely team, quiet, clean and tidy workers, on time and on budget, attention to detail exceptional. You cannot tell the difference between the 5 year old deck and the new extension. Highly recommend Elite Decking and Decking Perth.

As an ordinary DIY supported by a Team of Rockstars to achieve a tremendous result and nothing was too much trouble Cristian and Cassandra.
We were seeking a good quality decking oil for our garden landscaping and out-door shower project. We found the reviews on-line for Cutek Extreme Clear wood preserver were very good and suited us as it is absorbed by the timber thereby ensuring greater life expectancy and a great grain enhancer. In addition re-coating every 18mths to 2yrs appealed as the timber only requires a high pressure wash and a dry off period before re-coating. No sanding required. We chose a New Bronzetone tinter to deepen and enrich the merbau timber grain for an excellent aesthetic finish. Next Project the pool deck!
