I am super pleased with this product! Works very well on wood & concrete. Removes moss with ease. No strong odor. Great!

I tried this for 30 minutes on green algae on my painted wooden deck on a section that was 10 x 10 ft. Did not make a dent with bucket and brush!I then used a one to one ratio of product and water and it worked better. Please know that you must not let it dry and must rinse it off. This was the only way it worked for me on older algae. The brand new, light algae came off must easier. Just FYI.

Gentle on the hands, yet destroyed dirt and grime. A little scrubbing was necessary, but that may have been because it was soooo very dirty.

I used this to soak my wood fence and stairs, then pressure washed. It made cleaning faster compared to not using any soap solution. No smell. Very pleased with results, how much surface area it covered, and how it sped up the cleaning process. Will buy again.

Used on our deck, did not work as well as I hoped. Applied and rinsed with pressure washer, had to go back and scrub with a brush. Some dirt and algae still remained.

I have a 3 year old white vinyl fence which had gotten really dirty from tree sap, bird poop, and lantern fly dew droppings. Hosing it down would no longer suffice. I tried Simple Green oxy solve, 12 oz of solution per 2 gallons of water as stated in instructions. I cleaned my entire fence (75 ft long, 6 ft tall) both sides, with just three 2 gallon buckets and a soft brush. The pictures speak for themselves. The stuck on grime releases quickly. I cleaned from the bottom up and rinsed from top down. My fence looks brand new. I am extremely satisfied with the results. I would highly recommend.

Used this on a wood deck over water. Used the "soap" (low pressure nozzle) of the pressure washer. Great that it's safe to use around water. Cleaned horizontal surfaces great. Vertical surfaces that I couldn't get direct spray didn't remove much mildew and algae (supports, beams, outside of railing, etc.). The project looks unfinished so I have to find a different way to get the outside vertical surfaces. 5/5 for pretty clean and non toxic. Minus 1 because it didn't get the job done

This product did a great job removing the built up dirt and pollen stains on the stockade fence. Just fill the soap port on your power washer and follow the directions on the bottle It cuts through stains and dirt leaving quickly and easily. I don’t think you will be disappointed.
