## Overview

DEFY Composite Deck Cleaner is a powerful, oxygenated bleach powder designed to deep clean composite wood surfaces by removing dirt, black stains, and weathered graying caused by UV exposure. Its biodegradable, plant-safe formula ensures effective cleaning without damaging wood fibers or surrounding vegetation. Ideal for prepping decks before sealing, it also doubles as a versatile cleaner for fences, siding, and more, delivering professional-grade results while protecting your outdoor environment.

## Description

DEFY Composite Deck Cleaner is a safe, oxygen bleach deck cleaner that effectively removes black stains caused by dirt, grime, and weathered graying from composite wood surfaces. Unlike chlorine bleach, this environmentally friendly deck cleaner is biodegradable and will not harm composite wood fibers, pets, grass, or most plants. Using a chlorine bleach harms the wood as well as the vegetation surrounding the deck. DEFY Composite Deck Cleaner is a safe, powdered concentrate that is mixed with water to safely clean and restore the natural beauty of exterior, composite wood decks.

Review: Works great!
Review: This product is fantastic for cleaning composite decks. As the owner of a professional pressure washing company, I can tell you that pressure washing alone can damage composite surfaces. While it may remove dirt, it often leaves behind marks and streaks. Some people resort to using bleach or pool shock mixtures to eliminate moss and algae, but these can fade the color of your deck. In my experience, this product is currently the best solution on the market. Although it may be a bit pricey, it’s worth it for preserving your deck. Simply mix two measurement cups with hot water (it works with cold water too, although the powder dissolves more slowly) and spray a small area, letting it sit for a couple of minutes. This will help lift the dirt from your deck. Then, use a brush to scrub and rinse with a pressure washer—just keep the nozzle at a safe distance. This method effectively cleans without damaging the surface. Additionally, this product works wonders on painted wood siding. It loosens dirt, which you can then rinse off with a garden hose or pressure washer. We often use it to detail the wood siding on higher decks where dirt accumulates deep in the planks—it works like a charm. One area for improvement would be for the company to include a measuring cup with the product again. They may have removed it to cut costs, but not having it makes it challenging to measure the right amount for a one-gallon sprayer. So please, consider reintroducing the measurement cup!

*by R***N on 4 May 2017*

We cleaned our new BamDeck composite deck. We used two bottles of the powder, mixed in ten gallons of warm water total, for the whole 1,600 square foot deck. We applied it with a garden sprayer in small sections, then let it sit as directed, and brushed with a soft-bristle brush (as recommended by the composite manufacturer) before hosing it off. I recommend washing early in the morning, or later in the day when there is no direct sun if possible. If you apply in the sun, it's more difficult to keep it damp while it sits for ten to fifteen minutes as directed. The deck looked beautiful when we were finished. My only complaint is the high cost per bottle for a cleaner. However, we should only need to use it twice a year to keep the deck like new.
