How To Clean Your Composite Decking? In-Detailed Guide

Composite decking is much easier to clean than many other decking options. Solid wood decks require extensive maintenance and care, while composite materials only need a fraction of that attention. However, the reduced need for maintenance doesn’t mean you can leave your decking unattended. Composite decking is also a popular choice for homeowners looking to create stylish and low-maintenance outdoor spaces.

Thorough maintenance is key to keeping your composite decking looking beautiful for as long as possible. This guide will walk you through the best ways to clean your composite decking efficiently and safely.

Why Is Regular Cleaning Essential For Composite Decking?

Do you know that composite decking is designed to be durable, but exposure to dirt, moisture, and organic debris can lead to stains? Sometimes, it can also lead to mould growth and surface wear over time. So, cleaning your deck regularly helps: 

• Reduces stains from leaves, food, and spills
• Prevent mould and mildew buildup
• Maintain the original colour and finish
• Extend the life of your decking

By following the right cleaning routine, you can enjoy a beautiful outdoor space year-round. 

Why Are Composite Decks Easier To Clean?

Composite decks were made to provide homeowners with a low-maintenance option in comparison to conventional lumber decks. They’re made with an aggregation of vinyl/plastic and timber, lined with vinyl treatment.

The amount of wood varies depending on the type of composite decking, with many products having between 40-70% wood. In the end, antifungal chemicals and other preservatives help to treat and protect wood materials from rot.

Remember, the combination of timber and vinyl makes composite decks durable and less difficult to clean than decks crafted from wood alone. They nevertheless want some maintenance to look beautiful and inviting. No doubt, you can clean them just by using tools you have around the house.

The Composite Deck Cleaning Process 

Before you begin with the cleaning process, you are requested to gather the following tools and materials to clean your composite decking effectively:

• A soft-bristle brush or broom
• A bucket of warm water
• Mild soap or composite decking cleaner
• A hose or pressure washer (on a low setting)
• A sponge or cloth for spot cleaning.

1. So, after gathering these tools and materials, you need to follow the below 6 basic steps to clean your composite deck. 
2. Clear your entire deck of any furniture or objects that would get in the way of the cleaning process.
3. Using the broom, sweep the whole area and take away any leaves, debris, and extra dirt.
4. Spread warm water over the deck to get it ready for soap. Don’t worry about wetting every single inch; just spread it out the best you can.
5. Mix soap and hot water, much like the ratio you would possibly use to scrub your dishes.
6. Dip the deck brush into the bucket of soapy water and begin scrubbing your deck. Don’t be afraid to apply significant pressure to clear away as much dirt as possible—composite is hardy and can take it.
7. Once you’ve scrubbed the deck, take a hose and rinse away all the soapy water. The sun will take care of the drying part.

How To Maintain Your Cleaned Composite Decking?

After completing the cleaning process and to uplift your garden furniture, you need to keep in mind the below-mentioned maintenance tips.

1. Clean Your Composite Deck Regularly 

Regular sweeping and dusting will need to be combined with a gentle, soapy clean from time to time. This could be needed when cleaning up after a party when food has been spilt on the deck, after a storm or wet season where wet leaves and moisture have sat under your furniture for some time, or just from everyday dirt build-up.

Just like how the regular vacuuming of indoor floors doesn’t stop the need for mopping, your composite deck will need a wash every now and then.

2. Use The Right Stain Removal For Your Composite Boards

Composite decking is not stain-resistant. The ideal answer to stains is to avoid them by cleaning up spills and messes straight away, but stains do still happen sometimes. Oil-based stains can come from things like BBQ splatter or sunscreen. A household degreaser can work well for these stains.

For more stubborn stains, you can try a harder brush than you would generally use for cleaning, brushing lightly with the grain but avoiding scratching at and compromising the surface.

3. Stop Mould Before It Has Time To Grow

Like stains, mould and mildew should ideally be avoided with regular care and cleaning. Mould and mildew will usually occur where moisture and dirt have been allowed to sit for long periods. This makes moisture management important, and things like drainage should be considered when planning your deck.

Avoid using rugs, mats or furniture that will block the gaps or holes between boards and prevent proper drainage.

4. Skip The Pressure Washer

When stains seem stubborn or the build-up of dirt or grime is extensive, it can be tempting to try and find quicker cleaning methods. Always avoid pressure washing composite decking. Pressure washers can damage and remove the finish of even the best weatherproof composite decking boards, reducing their durability and lifespan.

5. Resist The Temptation To Paint, Stain, Or Bleach Composite Decks

Don’t use any paint or staining products on your composite decking. It will void your warranty and rarely ends up giving you the result you’re looking for. Never use concentrated chlorine bleach, even if it’s in a ‘deck cleaner’ solution. Bleach is corrosive and will ‘eat’ at the surface of whatever it’s applied to, wearing down the integrity of the surface of the composite decking.

Some Common Mistakes To Avoid When Cleaning Your Composite Deck

Many homeowners make cleaning mistakes that can harm their decking. Below are some common mistakes to avoid:

• Using a wire brush
• Applying undiluted bleach
• Using a pressure washer or high-settings
• Ignoring stains

Thus, you should sweep and rinse your deck once a week; deep cleaning (scrub with soap) should be done every 1-2 months. Make sure to indulge in performing a thorough cleaning before and after winter to maintain durability.
