How to Clean Fiberon Decking

Cleaning and caring for Fiberon decking can seem intimidating, but with the right knowledge and preparation, it’s an easy process that anyone can do! In this blog post, we’ll walk you through step-by-step instructions on how to clean Fiberon decking so your backyard looks its best all season long. So if you’re looking for tips on keeping your Fiberon in perfect condition – read on!

What Is the Best Thing to Clean Composite Decking with?

To clean your Fiberon composite decking, a combination of soap and water is best. It’s important to use a mild detergent that won’t damage the surface or leave behind residue. A scrub brush helps loosen dirt and debris from thieves in the boards, but a strong power washer should not be used as it can damage the boards.

If there are tough stains or mildew, you can use a diluted bleach solution (1/2 cup of bleach to 1 gallon of water) and a scrub brush to address these areas. Be sure to rinse off any residual soap or bleach with clean water after cleaning.

For regular maintenance, sweep your composite decking with a broom or leaf blower regularly and hose it down occasionally. This will help keep dirt and debris from building up in the grooves of your boards and prevent staining.

You may also consider applying a sealer to protect against long-term exposure to moisture and sun damage.  Be sure to check with the manufacturer for specific recommendations on which products you should use on your Fiberon decking.

Does Fiberon Decking Fade?

Fiberon decking is a popular choice for homeowners who want durable and low-maintenance outdoor decking. It is made from recycled wood fiber and high-grade polyethylene plastic, so it is more resistant to weathering than traditional timber decking.

 Sweep Your Composite Decking

Fiberon decking is generally very resistant to fading and discoloration. It has a protective cap layer that helps protect it from UV rays and other environmental factors that could cause fading. This means that you won’t have to worry about your decking losing its vibrant color over time.

That said, Fiberon decking can still fade if it isn’t properly maintained. If you do not clean it regularly and apply a sealant or protective coating every few years, then the sun’s UV rays can cause the colors to fade. To keep your decking looking its best, it’s important to clean it regularly and apply a protective coating as needed.

10 Methods How to Clean Fiberon Decking

1. Regular Sweeping

Regular sweeping is an essential part of maintaining a clean Fiberon deck. Use a broom with stiff bristles to remove loose dirt, leaves, and debris. Start at one end of the deck and work your way across, sweeping the debris toward the edges.

Be thorough, paying attention to corners, gaps between boards, and any other areas where debris may accumulate. Sweeping your deck regularly prevents dirt from embedding into the surface and helps maintain its appearance.

2. Mild Soap and Water

For routine cleaning of Fiberon decking, a simple mixture of mild soap and water can be effective. Fill a bucket with warm water and add a small amount of mild liquid dish soap. Dip a soft-bristle brush or a mop into the soapy solution, wring out excess water, and scrub the deck surface gently. Work in small sections, moving with the grain of the boards. Rinse the area thoroughly with clean water to remove any soap residue.

This method is suitable for removing general dirt, stains, and light grime. While it is effective for most casual cleaning tasks, more heavily soiled areas may require a stronger cleaner. Although mild soap and water is safe to use, it is important to refer the manufacturer’s specific care and cleaning recommendations for your Fiberon decking product.

3. Pressure Washing

Pressure washing can be used to deep clean Fiberon decking, particularly if it has accumulated stubborn dirt, algae, or mold. Before starting, ensure that your pressure washer is appropriate for use on composite materials and has an adjustable pressure setting. Use a wide fan tip nozzle and hold the wand at least 12 inches away from the deck surface to avoid damage.

Apply a Sealant or Protective Coating

Begin by pre-soaking the deck with plain water to loosen the dirt. Then, work in small sections, moving the wand back and forth in the direction of the boards. Take care not to linger in one spot for too long, as it may cause damage. After pressure washing, rinse the deck thoroughly.

4. Vinegar Solution

A vinegar solution can be an effective natural cleaner for removing mildew and mold from Fiberon decking. Mix equal parts white vinegar and water in a spray bottle. Spray the solution onto the affected areas and allow it to sit for a few minutes to penetrate the stains.

Then, scrub gently with a soft-bristle brush or sponge. Rinse the area thoroughly with water. Vinegar has natural antimicrobial properties that can help eliminate mold and mildew, leaving your deck clean and fresh.

5. Baking Soda Paste

Baking soda is a gentle yet effective cleaner that can tackle stubborn stains on Fiberon decking. Create a paste by mixing baking soda with water until it forms a thick consistency. Apply the paste directly to the stain and let it sit for about 15 minutes.

Use a soft brush or sponge to scrub the area gently. Rinse with water to remove the baking soda residue. Baking soda is a non-abrasive cleaner that can help lift stains without damaging the deck surface.

6. Oxygen Bleach

Oxygen bleach is a safe alternative to chlorine bleach and can be used to clean Fiberon decking without harming the environment. Follow the manufacturer’s instructions to prepare the oxygen bleach solution.

Soap and Water is Safe to Use

Apply the solution to the deck surface and let it sit for the recommended time. Scrub the area with a soft brush or mop to loosen dirt and stains. Rinse the deck thoroughly with water to remove the bleach residue. Oxygen bleach is effective in removing tough stains, such as grease, oil, and wine.

7. Commercial Composite Deck Cleaner

There are several commercially available composite deck cleaners specifically formulated for cleaning Fiberon decking. These cleaners are designed to remove stains, dirt, and grime without damaging the deck surface. Follow the manufacturer’s instructions for dilution and application.

Typically, you’ll apply the cleaner to a wet deck, scrub the surface with a soft brush or mop, and allow it to sit for the recommended time. Rinse the deck thoroughly with water to remove any residue. Commercial composite deck cleaners are convenient options that provide effective cleaning results and help maintain the longevity of your Fiberon decking.

8. Chlorine Bleach Solution (Caution Required)

Caution: This method should be used sparingly and only as a last resort for stubborn stains. Prepare a chlorine bleach solution by mixing 1 part bleach with 3 parts water. Apply the solution to the stained areas, ensuring to protect surrounding plants and vegetation.

Let the bleach sit for a few minutes, then scrub the area gently with a soft brush or sponge. Rinse the deck thoroughly with water to neutralize the bleach. Use this method with caution, as chlorine bleach can potentially lighten the color of the deck if used improperly or left on for too long.

9. Preventative Measures

Taking preventative measures can help keep your Fiberon decking clean and minimize the need for extensive cleaning. Place mats or rugs near entrances to collect dirt and debris before they reach the deck. Promptly clean up spills and stains to prevent them from setting. Avoid dragging heavy furniture or sharp objects across the deck, as they can cause scratches or damage the surface.

White Vinegar and Water in a Spray Bottle

Regularly trim nearby trees or bushes to reduce the amount of organic debris that falls onto the deck. By implementing these preventative measures, you can maintain a cleaner deck and reduce the frequency of intense cleaning sessions.

10. Professional Cleaning Services

If you prefer to leave the cleaning of your Fiberon decking to professionals, hiring a professional cleaning service specializing in deck maintenance can be a convenient option. These experts have the knowledge, experience, and proper equipment to effectively clean your deck while ensuring its longevity and beauty. They can assess the condition of your deck, identify the appropriate cleaning methods, and provide thorough cleaning and maintenance services.


In conclusion, knowing how to clean Fiberon decking is important for extending its lifespan and keeping it looking beautiful. Regular maintenance of your Fiberon decking is necessary to ensure that it stays in its best condition. For deep cleaning, a mix of warm water and soap should be used.

To maximize your outdoor enjoyment with a low-maintenance lifestyle space, use stain-resistant composite products such as Fiberon’s Horizon line. Its strong protective shield guards against fading, staining, and scratching, so feel free to choose colors without worry as these will stay vibrant for years to come. Now that you have learned all about cleaning Fiberon decking for optimal beauty and longevity put the knowledge into practice!
