We’ve been using this cleaner for years now, and I’ve got to say, it really works. I've tried other brands and they just don't work for us. Our house faces north, so we get mold twice a year, especially on the metal roof and pool screen. This cleaner does the trick! I’ve found the version you dilute yourself with water (not the hose version) works a bit better, but even with the hose, it still gets the job done. I just spray it on, let it sit for a bit, rinse and the mold is gone without any scrubbing. It’s been great for keeping the roof clean!

Easy to use. Product works exactly as advertised - spray on, let sit on surface, rinse. Cleared my north-facing siding all the way up to second story without need for ladder. Just my hose and the cleaning solution with included dispenser adapter. If you apply and scrub, your surface will be like new. I chose just to apply and rinse. Siding still looks fresh and clean, though if you walk right up to it, you can see some minimal, faint residue in some areas. For sake of convenience and time, apply and rinse works great. Only reason it's not 5 stars is that there was some minimal leakage during shipping due to the caps of each of the bottles allowing small amounts of solution out - likely due to the boxes being stored incorrectly in inventory and/or during shipping.

I wasn’t sure how well this would work, but it really surprised me. I found this after looking up some reviews on Youtube. I used it on some vinyl siding that had green algae stains, and they cleared up with almost no scrubbing. The hose-end sprayer made it super easy to apply—just connect and go. I liked that I didn’t have to mix anything. Definitely made my outdoor cleanup way easier. Attached are some before and after pictures. You can clearly see a big difference. In person, it looks way cleaner.

I have never given a 5 star review for the hundreds of products I've bought from Amazon. If I could I'd give it more. I have screens on the second story that were originally beige that had turned black. While I was playing out my work plan I noticed that between and above and below these windows was covered in green mold as well. I bought the two pack thinking I'd have to do two treatments. I was shocked when I turned the nozzle setting to the water only setting and started to rinse it off. All the mold on the screens was gone in just a couple minutes. I sprayed the entire area first and after reading the instructions and word with the knowledge that "don't let it dry". I decided to rinse it ad soon as I finished spraying it on. I'm glad I did. It took me 3 - 5 minutes to spray the whole area which is approximately 20' W x 10' tall and I was ready to dance a jig when I saw how clean it was. I came back to reality and thought I'd better hold off on that dance until it dries. Well, I wasn't disappointed. About an hour later I went out to look at it and was was like brand new. I've got the extra gallon so now I'm going to do the chimney on the other side of the house. But this product, you won't be disappointed.

Hadn't washed my vinyl siding in years on the North side of my house. Ordered this stuff thinking it would at least cut down on my pressure washing. Boy was I wrong, it completely eliminated the need to pressure wash. This stuff worked amazing. Siding looks brand new and white.

My two containers both had leaks, so I think I got probably most of what I purchased, but some had definitely leaked out and they were slippery as can be!First let me say I started off by watching a lot of YouTube clips! I own an electric power washer, and vinyl siding, and have used it ever since I switched from a gas pressure washer, and it takes a couple hours to get it done, with of course the fear of blowing off a piece of siding, which has happened even being 90° to it it still happens!So I was very interested in this product! And it works... But at first I use the default setting because the siding isn't very high off the ground, and I didn't see any bubble action, kind of that soapy action... So I went ahead and pulled the red pin/cap, and immediately saw the action, this is from about 4 to 6 ft away, soaked the whole building, on full blast with the red cap pulled you'll only get a couple of minutes out of this! It will go fast! And the way you can tell you're getting to the end, as it'll start sputtering, and you'll look down and see your canister almost collapsed! So if you don't take note of this, you might just be rinsing off the stuff you applied! Which I think happened with my first jug! Because the results were not remotely impressive! Like at all, except for an area at the far corner where I had long sprayed it, and I think the fluid had time to work. Next is, pull the red cap anyway! You can regulate the flow by that same twisty handle! If you go 50% to rinse(and again this is assuming you have used the whole amount of the jug! Empty!) Then then you get mostly that same effect from the first before you pull the red cap, then when you want the blast, just twist the handle all the way to full rinse!Which I did, to my disappointment.Okay, luckily I bought two jugs, though also unlucky because now spent more money than I should have on this! It's about 50% humidity, sitting around 90° with a 8 mph wind. I have huge shade trees, so also the sun's going down so plenty of shade. Let the first round kind of dry, hit it with the second jug, this time with the red cap pulled, and it did as one would expect, although not great in one area... Oddly enough the area I had good results with, with the first jug!Also if you do end up using it on decking, make sure you rinse it thoroughly, it is very soapy slippery, but it probably was going to be that way anyway if you had some green stuff sitting on it!
