Simple Green Oxy Solve Deck and Fence Pressure Washer Cleaner, Colorless to Pale Straw, Unscented, 128 Fl Oz (Packaging May Vary)U.S. EPA Safer Choice[Amazon-developed Certification] Compact by Design

Worked great on old gray cedar fencing. No damage to grass.

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.

My deck is four years old and has oxidized or weathered a little. While this product didn't remove all the oxidation, it did improve the deck quite a bit. I've tried several other products and cleaning solutions and so far this is the best.

Chose this product as it is safer for vegetation and pets. I couldn’t be more pleased with the outcome. Followed up the application with a rotary pressure washer.

I purchased this because of the reviews but I can't give it the rave reviews others have. I used it on my back porch and after hours of going back and redoing, it came mostly clean. I will not buy this product again. It is not worth even the smaller price that they are asking.

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

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

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.
