Rated 5.0 out of 5.0 by MidwestDIYer AMAZING on wood.
We have been fighting raccoons for about 5-6 years, they like to come on our patio with their dirty paws and get mud, animal waste and fur clumps all over. Between that, and the constant rain water- the wood was discolored green and black in places.
I rented a power washer last year from Home Depot, and it didn't get nearly as much dirt and grim off the exterior, wood and metals as this cleaner did. Seriously. Its easier, costs less and does a better job. Just buy this stuff.
The photos I took don't do the product justice, the before almost looks like its stained a nice brown, but the wood is covered in years of slimy brown filth because the wood never got sealed. You didn't want to stand on the deck without shoes it felt so dirty and gross. Now its clean and we can seal it with stain or something to make sure this never happens again.
Someone else pointed out that its pretty much bleach, and it definitely smells like that. You'll end up smelling like a pool.

Rated 1.0 out of 5.0 by Whoaboy Did not work for me!
We had been laboriously power washing our concrete drive and sidewalk and decided to try this product. First let me say that on concrete the bottle does not go far so it is going to take a lot of product to do any walkway or drive. We allowed it to penetrate for the recommended 15 min then using our power washer rinsed . It didn't make much difference than straight lower washing so we were quite disappointed . Why spend money on a product that only works minimally at best. Tried straight cheap bleach and wouldn't you know it.. Worked better than this stuff !

Did not do anything the bottle promised. Don't even bother trying it.

Worked exactly as it said on the label. I sprayed it on the shaded side of my house that has wood siding, using a 1 gal pump sprayer, waited 30 seconds and hosed it off. The green mold/algae disappeared as I watched. I'll be buying more for the rest of my house very soon.

Rated 5.0 out of 5.0 by Buzzy Works Great!!!
I live in the Puget Sound area of Western Washington. We have many evergreen trees surrounding our sundeck that continuously drop pollen, pine needles, and tree debris onto our cedar deck. After just replacing all the cedar decking last summer, I wanted to clean the deck without tearing up the new cedar with a power washer. I applied this cleaner as directed with a 2 gallon pump sprayer and used a scrub brush with a long broom handle attached. I just gave it a gentle scrub once product was applied. Once I had about 10 minutes of dwell time, I spent plenty of time thoroughly rinsing the deck. The deck was 12ft. X 22ft and the job was done in about 2 hours including the railings. I did a real light sanding with a random orbital sander & 80 grit sanding disk. Then I applied a coat of Penofin semi-transparent stain (as directed by stain manufacturer) and the deck looks better then when it was new last summer. I feel that this 30 Second Outdoor Cleaner saved me a great deal of time and labor. This was so easy, I plan to redo my deck like this every year in the month of May.

I am staining a 5 year old screened in porch and ramp. I have no gutters along ramp by the house so mold builds up quickly and it was black. This brought it back to almost new. Applied 1.1 and used a handled deck brush from HD to apply. I waited for minute and the scrubbed with deck brush and rinsed. Had a few spots that I had to do twice but I did have some heavy mold, like I said. I did not have a pressure washer but this did just fine. About 2 hours to really get the long ramp and banister good and clean. Started staining banister this morning and will stain ramp tonight. The rest I can do a little at a time depending on the weather and dampness. I would use again. It did take 1 gallon to do the ramp and banister. No odor that I would tell. Did not burn or sting. I did put on old clothes but saw no problem when I got through.

Tried to clean the black slime off concrete that is so common in the Puget Sound region. The product did not go very far and I saw only minimal improvement. I had hoped to avoid power washing, but it looks like that is what I will have to do!
