Before You Start
Identify the deck area and remove outdoor furniture and planters. Inspect for loose boards or nails and address any repairs before cleaning. Mix cleaning solution according to manufacturer guidelines and test a small, inconspicuous section first. Use eye protection, gloves, and avoid cleaning on very hot or windy days to prevent streaking. Allow for a dry, sunny window of 2–4 hours after cleaning before exposing the deck to heavy traffic.
Step-By-Step: How To Clean Azek Decking
- Clear the deck and rinse the surface with plain water to remove loose dust and debris.
- Apply a diluted cleaner formulated for PVC and composite decking, following the product’s instructions. Do not use household bleach or highly acidic cleaners unless specified by the manufacturer.
- Let the cleaner sit for 5–10 minutes to break down mildew and outdoors grime; avoid letting it dry on the surface.
- Gently scrub using a Azek decking cleaner brush or a vinyl deck cleaning brush long handle to lift dirt from the surface without scratching.
- For stubborn spots, reapply cleaner and scrub with circular motions, focusing on shaded areas where mildew tends to accumulate.
- Rinse thoroughly from one end to the other with a hose or a pressure washer for vinyl deck cleaning. Use a soft wash spray nozzle for pressure washer to reduce pressure and protect the surface.
- If using a pressure washer, keep the nozzle at a low angle and maintain a few feet of distance to avoid gouging around edges or fasteners.
- Allow the deck to air dry completely before replacing furniture or adding a protective sealant, if recommended by Azek. Reinspect for any remaining stains and repeat as needed.
- Store tools and cleaners in a cool, dry area. Rinse brushes and rinse the cleaning solution from all handles to prolong tool life.
- Document the cleaning schedule for seasonal maintenance to prevent buildup and maintain the deck’s appearance and safety.
Troubleshooting
| Symptom | Likely Cause | Fix | Prect cautious |
|---|---|---|---|
| Streaks after rinsing | Improper rinsing or soap residue | Rinse again with clean water, use a wider nozzle | Rinse thoroughly; avoid mixing cleaners |
| Milky or cloudy surface | Detergent residue or incompatible cleaner | Rinse with lots of water; avoid harsh cleaners | Test cleaner on a small area first |
| Scratches after scrubbing | Using abrasive tools | Switch to a soft-bristle brush; no steel brushes | Use gentle pressure |

Look for cleaners labeled safe for PVC or composite decking, and select brushes with soft bristles designed for smooth, non-porous surfaces. For those who prefer less physical effort, a long-handled brush and extension pole can reduce bending and allow thorough cleaning from ground level.
