Maintaining and cleaning PVC decking

Maintaining and cleaning PVC decking is straightforward and will help preserve its appearance and longevity. Here’s some tips to help:

1. Routine Maintenance

  • Sweep Regularly: Use a soft-bristle broom or a leaf blower to remove dirt, leaves, and debris to prevent staining and buildup.

  • Rinse with Water: A garden hose is usually sufficient to wash off dust and light dirt.

  • Protect from Scratches: Avoid dragging heavy furniture or sharp objects across the surface. Use furniture pads under chairs and tables.

2. Deep Cleaning

  • Use a Mild Soap Solution: Mix warm water with dish soap or a PVC-specific deck cleaner. Scrub with a soft-bristle brush to remove grime.

  • Pressure Washing: You can use a pressure washer, but keep the pressure below 1,500 psi and maintain a safe distance (at least 8–12 inches) to avoid damage.

  • Mould and Mildew: Use a solution of water and white vinegar (1:1 ratio) to spot-clean areas with mould or mildew. For stubborn stains, consider a PVC deck cleaner with mould-fighting properties.

3. Handling Stains

  • Oily or Greasy Stains: Clean immediately with a degreaser or soapy water. Avoid letting oils sit, as they can stain over time.

  • Rust Stains: Use a specialized deck cleaner or oxalic acid (found in wood brighteners) to treat rust stains.

  • Tannin or Leaf Stains: Rinse thoroughly after scrubbing with soapy water or a mild cleaner.

4. Prevention Tips

  • Protect from Heat and Chemicals: Avoid placing hot objects (like grills) directly on the deck, as PVC can warp under heat. Always use a grill mat.

  • Avoid Harsh Cleaners: Stay away from abrasive cleaners, steel wool, or bleach, as these can damage the surface.

  • Prevent Standing Water: Ensure proper drainage and sweep off pooled water to prevent mildew.

5. Seasonal Care

  • Winter: Use a plastic shovel for snow removal to avoid scratching. Avoid using sand or salt, as it can damage the surface.

  • Spring: Inspect for damage, clean thoroughly, and check for any mould, mildew, or stains that may have developed over the season.

6. Long-Term Protection

  • UV Protection: Most PVC decking is UV-resistant, but periodically cleaning and removing dirt can help maintain its appearance.

  • Sealing (if recommended): Some manufacturers may suggest sealing the deck for extra protection, so check the product guidelines.
