How To Clean Fiberon Decking: Care & Maintenance Guide

Fiberon decking is built for long-term beauty with minimal upkeep, but even low-maintenance materials need routine care to stay in top shape. If you want to know how to clean Fiberon decking, this complete guide walks you through the right steps to maintain your outdoor space safely and effectively.

Whether your deck is made with Fiberon Sanctuary, Promenade, Good Life, ArmorGuard, Veranda, Concordia, or Paramount PVC, proper cleaning keeps the surface looking vibrant while protecting the board’s cap and performance.

Regular Cleaning for Dirt and Debris

Regular maintenance is the first step in understanding how to clean Fiberon decking correctly. Dirt, pollen, and organic matter can collect on any outdoor surface, including capped composite boards.

Steps to Clean Dirt and Debris on Fiberon Decking:

  1. Clear Loose Debris:
    Sweep the deck or use a leaf blower to remove leaves, seeds, and dust.
  2. Rinse the Boards:
    Spray the deck with water to clear fine particles and open drainage gaps.
  3. Apply Mild Soap Solution:
    Use warm water with a mild household cleaner or composite deck cleaner.
    Fiberon approves pump sprayers for even coverage.
  4. Scrub Safely:
    Use a non-metal brush:
    • Soft nylon brush for Symmetry / Good Life
    • Soft brass brush for all other Fiberon lines
      This prevents surface damage.
  5. Rinse Thoroughly:
    Wash off soap completely to avoid film and residue.

Using a Pressure Washer

You can use a pressure washer, but only within Fiberon’s strict guidelines to prevent damage.

Power Washing Tips for Fiberon Decking:

  1. Stay Under 2500 PSI:
    Keep pressure low and hold the nozzle 12 inches above the boards.
  2. Use the Right Nozzle:
    Only use a wide fan tip or oscillating nozzle to reduce pressure impact.
  3. Wash in the Grain’s Direction:
    Move the nozzle following the board pattern for safe cleaning.
  4. Pre-Treat With Cleaner:
    Apply approved deck cleaner first, then lightly scrub.
  5. Never Let Cleaner Dry:
    Work in small sections and keep the surface wet until rinsed.

Addressing Stains and Spills

Accidents happen, and quick action prevents long-term staining.

How to Clean Stains on Fiberon Decking:

  1. Clean Spills Immediately:
    Acting fast keeps stains from setting into the surface.
  2. Use Soapy Water:
    Most stains lift easily using mild dish soap and warm water.
  3. Use Approved Cleaners for Grease:
    Fiberon recommends:
    • Fantastik®
    • De-Solv-It® Citrus Solution
      These help remove grease, oil, gum, and adhesive.
  4. Rinse Completely:
    Always flush chemicals off the boards.

Removing Mold and Mildew

Mold can develop when moisture, shade, and organic debris combine.

How to Clean Mold and Mildew on Fiberon Decking:

  1. Use a Mold-Approved Cleaner:
    Fiberon recommends 30-Seconds® Outdoor Cleaner for effective mold removal.
  2. Keep Deck Wet During Cleaning:
    Prevent cleaners from drying on the surface.
  3. Scrub Gently:
    Use the correct soft brush for your Fiberon deck type.
  4. Rinse With Water:
    Remove all residue to prevent regrowth.
  5. Clean at Least Once a Year:
    Humid or high-pollen areas may require more frequent cleaning.

Cleaning Concrete, Cement, Mortar & Stucco Dust

Construction dust can permanently discolor composite decking if ignored.

How to Clean Construction Dust on Fiberon Decking:

  1. Cover Decking During Masonry Work:
    Prevent mineral deposits and chalk dust from settling.
  2. Avoid Colored Chalk:
    Use white chalk or baby powder – colored chalks can stain permanently.
  3. Use Mild Cleaners for Mineral Haze:
    Remove masonry residue with soap and water or composite deck cleaner.
  4. Remove Dry Dust Before Rinsing:
    Sweep or blow off loose concrete or cement dust before adding water.
  5. Keep Masonry Materials Dry:
    Wet stone, cement, or mortar can release minerals that leave white stains.
  6. Rinse in Small Sections:
    Keep the deck wet while cleaning and rinse each area before moving on.

Handling Hard Water Stains

Hard water can leave white spots on composite boards.

How to Remove Hard Water Stains From Fiberon Decking:

  1. Apply White Vinegar:
    Vinegar helps dissolve mineral deposits.
  2. Let It Sit Briefly:
    Give the vinegar a minute or two to soften the buildup.
  3. Scrub Gently:
    Use a soft brush to loosen the mineral residue.
  4. Rinse Thoroughly:
    Flush with clean water to remove loosened buildup.
  5. Repeat if Needed:
    Stubborn mineral spots may require a second application.
  6. Dry the Area:
    Allow the boards to air-dry so no new water spots form.

Winter Care

Fiberon decking performs well in winter, but you still need to protect the surface.

How to Handle Snow and Ice on Fiberon Decking:

  1. Use Plastic Tools Only:
    Plastic shovels or nylon-bristle brooms prevent scratches.
    Avoid metal edges entirely.
  2. Use Calcium Chloride or Rock Salt:
    Avoid color-dyed ice melt products – they can stain.
  3. Do Not Use Sand:
    Sand is abrasive and can scratch the deck surface.
  4. Shovel Parallel to Boards:
    This reduces risk of gouges.
  5. Sweep Residue After Melting:
    Remove leftover ice melt granules to prevent tracking and surface buildup.
  6. Rinse the Deck in Warmer Weather:
    A quick rinse removes any remaining salt or residue once temperatures rise.

Managing Static Electricity

Dry climates or certain home conditions may cause static buildup.

How to Reduce Static on Fiberon Decking:

  1. Clean Loose Debris First
  2. Apply ACL Staticide® (Diluted 1:39):
    Spray or mop the entire surface and let it dry naturally.
  3. Avoid Walking Until Dry:
    Let the anti-static coating set fully for best results.
  4. Redirect Dryer Vents:
    Keep dryer or heat pump vents pointed away from the deck to reduce static buildup.
  5. Minimize Synthetic Rugs:
    Avoid rubber-backed or synthetic mats that can increase static charge.
  6. Clean Periodically:
    Regular cleaning reduces dust and debris that contribute to static electricity.
