Azek decking is known for its low maintenance and lasting beauty, but it still benefits from regular cleaning to remove dirt, mildew, and stains. This guide provides practical steps using common tools and safe techniques to keep PVC and composite decks looking fresh without damaging the surface.
The following steps focus on gentle cleaning methods and the right equipment to protect the finish while achieving thorough results on Azek decking.
Quick Answer
Use a soft brush or scrubber, a mild cleaning solution designed for vinyl decking, and a low-pressure rinse. For stubborn stains, a vinyl deck cleaning brush long handle or an Azek decking cleaner brush helps reach tough areas. Avoid high-pressure washing that can damage the surface.
What You’ll Need
- Azek decking cleaner brush
- Vinyl deck cleaning brush long handle
- Pressure washer for vinyl deck cleaning
- Soft wash spray nozzle for pressure washer
- Extension pole for cleaning PVC decking
Before You Start
Prepare the area by removing furniture and rugs. Sweep away loose debris to prevent scratches during scrubbing. Test any cleaner on a small, inconspicuous area first to ensure no discoloration. Use a low-pressure setting on the pressure washer and keep the spray wand at a safe distance from the surface. Avoid high heat and harsh chemicals that can degrade the finish or void manufacturer warranties. Plan for a dry period after cleaning so the deck can air-dry fully.
