Composite Deck Cleaner

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!

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.

It's a little pricey, but nothing works better for cleaning composite decking. I really appreciated their suggestion to strain the solution through a paint filter if putting it in a sprayer so it won't clog the spray head.

Why did you pick this product vs others?:Did not work to remove the spots. Took color out of my deck!Stain removal:Zero

I use these types of products every spring. I use a sprayer to distribute the product, then let it sit a few minutes and then power wash. I have found other products that work better.

This product is amazing. It cleaned or mildew covered deck perfectly. We have a composite deck in full sun and the mildew loves it. The only problem was my husband's was impatient. The product does work best if you let it sit for the recommended time. Would definitely recommend to anyone!!

So glad to find something that works and is so easy to use - even the dirty spots near the bbq and under the planters came out with a little extra scrubbing. I have a large deck so we clean half of it at a time so we don't have to move the outdoor furniture up and down the stairs to the yard. Once we finished both sides and it was completely dry the deck was uniformly clean which is very important to me.

I think that a good power washer works nearly as well. The product did a fine job finishing up the deck after power washing it first
