Great product. I used it on my patio and outdoor siding that had built-up dirt and mildew, and it worked great. It was simple to use, just attached it to the hose and started spraying. Easily sprayed 40ft and I did not need to scrub at all and you could see the difference pretty quickly. What I liked most was that it actually delivered on what it promised without a lot of extra effort. A lot of outdoor cleaners claim to be easy, but this one really was. So far, very happy with it and would definitely buy it again.

Product work very well, the only problem I see is it doesn't spray the cleaner 40ft maybe 10ft. It would spray 40ft to rinse. A little miss leading other then that I would have gave it a 5 star

I've used hose-end outdoor cleaners before, mostly the typical mildew sprays for siding, and this one earned its spot in my garage pretty quickly. We've got a north-facing stretch of vinyl siding that goes green every spring, plus a wood fence that picks up algae on the shaded side, so I had plenty of test surfaces to put it through. Setup is genuinely simple. Twist the hose onto the nozzle, turn the dial to Spray, and go. The dial has clear Off, Water, and Spray positions, so you can rinse without disconnecting anything. The 40+ foot reach claim isn't marketing fluff either — I was hitting second-story siding from the ground without a ladder, which is the whole reason I wanted a hose-end version in the first place. Performance was the real surprise. I sprayed the siding, walked away for about seven or eight minutes, and came back to rinse. The green stuff was just… gone. No scrubbing, no second pass needed on most spots. The fence took a little longer to fully clear and one stubborn patch needed a follow-up application, but for something you spray and walk away from, results were impressive. The bleach smell is strong while you're applying, so I'd recommend doing this on a calm day and wetting down nearby plants beforehand like the directions say — I lost a couple of hosta leaves that got direct overspray before I figured that out. Build quality on the bottle and nozzle feels appropriate for what it is. The dial clicks firmly into each position and didn't leak where the hose connects. Bottle is sturdy enough that I'm not worried about it cracking if it tips over in the garage. A solid value for anyone dealing with mold, mildew, or algae on exterior surfaces who doesn't want to mess with a pressure washer. Worked better than the pump-sprayer concentrate I was using before, and being able to skip the ladder is huge.

We moved into a house with some problems. There were no gutters, and water and paint from the siding above ran down the exterior brick wall. We thought it best to mold treat it, so I got this Moldex outdoor cleaner. The cleaner bottle hooks to the hose easily. It's a little bit awkward to hold. It sprays in a horizontal arc. It's not a very pressurized spray, you should be pretty close up to whatever you are cleaning. I highly recommend doing this on a day with no wind at all. It will spray back on you in the wind. We pointed this at some of the paint stained brick. The marks in the first picture are where the previous owner tried to pressure wash the paint stain off and failed. The second picture is after the treatment with the Moldex. To my surprise it took quite a bit of the paint off. I just expected it to clean the bricks. You could see it melt off in real time, and it was pretty awesome. I also love the thought that it was getting rid of any mold from not having gutters, because the formula has bleach. The bleach smell is very strong. Wear a face mask while spraying it if you have sensitive breathing. It has a lot of bleach. You can adjust it between spraying the formula and more of the hose water, so you can rinse off areas that you treated with the hose water. The design makes sense. Overall, this is a unique, effective, and potent cleaner. Thank you.

I recently used the Instant Outdoor Cleaner with Bleach, and it turned out to be a very reliable solution for tackling stubborn outdoor stains. One of the best features is the built-in hose-end sprayer, which makes application incredibly simple, just connect it to your garden hose and you’re ready to go, no need for mixing or scrubbing right away. It sprays evenly and reaches larger areas like siding, decks, fences, and even concrete surfaces, saving both time and effort. The bleach-based formula is strong enough to break down mold, mildew, algae, and dirt stains that have built up over time. I noticed visible results within minutes, especially on areas that hadn’t been cleaned in a while. Another thing I liked is how well it clings to surfaces, giving the cleaner time to work before rinsing it off. For tougher spots, a light scrub can help, but in many cases, just spraying and rinsing is enough. It’s also great for seasonal cleaning, like refreshing outdoor spaces before gatherings or after harsh weather. The bottle size is generous, and one container can cover a decent area depending on usage. That said, since it contains bleach, it’s important to take precautions, wear gloves, avoid contact with clothing, and be mindful around plants and grass as it may cause damage or discoloration. It’s best to rinse nearby plants with water before and after use as a safety measure. Overall, this cleaner is a powerful, time-saving product that delivers fast and noticeable results, making outdoor maintenance much easier and more efficient.
