DEFY2 LB Wood Deck Cleaner Powdered Concentrate - For Decks, Fences, Siding, & More - Covers Up to 1,000 Sq. Ft.

This was a good wood cleaner for the outside of my house. It did the job.

Pictures really don’t do justice for how good this product works. I only bought it for a quick clean before staining-I didn’t even think my porch was that dirty. This product blew me away with how much dirt and stuff came up! Easy to use. I cleaned the wood with a $15 deck brush from Lowe’s.

Does a fantastic job of cleaning your deck, but make sure you use the Brightener afterwards to neutralize and give your deck a like new surface to stain.

Combination of cleaner and brightener addressed much of the prep for staining but they were no match for tannins from an overhanging oak tree.

Easy to mix up and did a great job of getting the mildew off my deck. My deck is exterior stained in a grey color and it left it as it was and just removed the dirt and mildew. It also works on aluminum so I cleaned some mildew off the side of the house too. I used it and rinsed and it definitely seems to be plant friendly as I saw no change in the surrounding grass, etc. It is pricey but this container should last a long time.

Did not clean as described. Looked the same as before. So I needed to power wash off and use a different cleaning method

Worked well to get dark green off the deck. Brushing is necessary. It was not just put it on and done. Using the brightener as next step made a difference.

I used this product to clean my deck, I bought my home 3 years ago and this was the first deck I have ever power washed, it worked very well and also cleaned my siding on my home. I would definitely buy it again.
