DEFY 2 LB Wood Deck Cleaner Powdered Concentrate - For Decks, Fences, Siding, & More - Covers Up to 1,000 Sq. Ft.

Didn't completely even out all the mildew difference on my deck, but I bet if I took it through a couple more passes, it would have. Makes cleaning deck boards super easy.

Absolutely works. I was hesitant in purchasing this since I have spent lots of monet over the years on deck cleaning that did not work.

The wood was black in whole sections. This took it to matching the replacement board we put down 6 months ago. I did buy the brightener but writing this review before I using that.

THE GOOD - I just connect the hose and sprayer to water down my 10' x 14' enclosed gravel covered dog run where the big dogs do their business. One NaturVet bottle is good for 1 treatment, but I spread it out of 2 treatments to save money if the oder wasn't too bac. Smells nice, but a bit on the strong side. THE BAD - I bought several of these over time...got kind of pricer after a while since it doesn't prevent future pee smells from quickly developing, especially during the summer. I have used Murphy's Soap Oil with water that does very well in getting rid of pee odor, but it gets still pricey over time. By the way, soaking and then hand washing smelly ice hockey gear with Murphy's Soap Oil and water will get rid of all smells. Works way better than anything out there to ridding the awful smell out of shin guards, elbow pads, gloves, helmets, and hockey bags. Any hockey parent will tell you hockey gear smell is the worst. MY CURRENT SOLUTION - I started mixing several tablespoons of baking soda (from Costco) with a gallon of water (empty milk cartons) and immediately spot treat each fresh pee spot with a squirt bottle (large Ketchup squirt bottle). This will hold down the smell quite a bit because baking soda will help neutralize the acidic urine that causes the smell. When the pissy smell starts to build up in the hot sun, I will fill a gallon size garden watering pail with soda water and add an 1/8 cup or less of Odor Ban (watermelon scented) to the solution. I then water the gravel area with this solution where the dogs peed on. I'll lightly water the gravel afterwards with the hose sprayer to prevent any possible iritation to the dogs' pad and to help the solution soak deeper into the ground. My dogs are trained to pee only on a 3' x 5' area. Works great. A gallon of Odor Ban is only $10, By the way, this solution works well on spot cleaning carpets...and also when used in a carpet cleaner machine where incontinent persons occasionally have a boo-boo or oospy.

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.

Did a great job of removing dirt and contaminates before using defy wood brightener.

Don’t buy this product unless you want arthritis in your elbows and wrists from scrubbing. I will go back to good ol Walmart bleach. Less work and better results.

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.
