Doesn't work at all
I chemically treated the whole side of the house five different times and soaked for about an hour and did it kill any mold or mildew or remove any stain whatsoever waste of time and money

That's not what we expect to hear, Jonathen! For the best results, it is essential that Rust-Oleum Jomax House Cleaner and Mildew Killer is mixed at the correct ratio with water and bleach. The solution also needs to be used within 3 hours of mixing to ensure it remains effective. For heavier stains, a second application may be needed and textured surfaces may require a light scrubbing.

    Worked great on white vinyl fence
    My fence was mildewed and in some spots covered in algae. Jonn my ax took care of all of it. Mostly gone with one spray but a few spots needed a second spray and scrubbing with a brush. Not much elbow grease involved. Sadly it’s not for driveways.

      Amazing!!!
      This stuff worked so well!! Very impressive! It was super bad green moss stuff growing all over the roof. Sprayed it once and it was all dead in just a couple of days! I did add 1 cup of concentrated bleach per gallon. Mix as recommended and just saturated all over. It took 4 gallons to spray this entire roof. No sweeping or scrubbing needed. Just spayed one time and walked away!! I will use this Jomax product again! ❤️LOVE it!!!

        This product worked so well! I was skeptical when it said no scrubbing needed but for the most part that is true. There were just a couple stubborn areas that needed some extra help. Just a tip-make sure you wet your plants under the area really well before the application to the house and after. This is important or you will kill your landscaping!

        Wow, I used to clean my siding of that green algae with bleach and brush, but Jomax mixed with bleach allows me to just spray it on and it’s gone! Amazing! What a work saver. Still have a hard time believing it could be that easy, but my snow white siding proves it is. Avoid the hassle of long reach brushing and buy Jomax!

        Been using for many years, has never disappointed me. I recommend for all outdoor washing projects. If put on according to directions, mildew and dirt are easily removed by rinsing or low level pressure wash.

        Use Jomax House Cleaner and Mildew Killer before you buy your paint, and you may decide not to paint. This product yields amazingly clean paint, and is very easy to use - no pressure washer needed. My paint looked so good after cleaning that painting wasn't necessary. I mixed the Jomax House Cleaner with bleach and water as instructed on the product label. I sprayed my painted house eaves, and carport with the Jomax mix using a backpack sprayer, and then rinsed about 10 minutes later with water from a hose. The amazingly clean paint was immediately visible, and looks even better after the surface dries. The attached photo shows a corner of my carport that was sprayed with Jomax, and rinsed with water. In the photo, you can see how clean the corner is, while the untreated ceiling remains very dirty. I also sprayed the Jomax mix on some mildewed bricks on my house, and rinsed. The treated area looks a little better one day later, but the results so far are not remarkable. If you are cleaning brick, spraying Jomax and and rinsing off will not yield immediate results. I highly recommend Jomax House Cleaner and Mildew Killer.

          Great product and at a good price
          JoMax is the best product I have ever used and will ever use to clean the surface of our house. It is great on wood, brick, stucco and even my concrete walks and drive. Easy instructions and the JoMax goes a long way, if you follow the instructions. I will always but JoMax for any cleaning job, no matter what the surface. Truly a great product and no improvement is need in this product. Just great and speed my time in cleaning!

          Outstanding Cleaner!
          I had purchased vinyl siding for my house in 2007. My wife recommended I purchase an extra 3 boxes for an addition we were planning. However, that project was delayed. 9 years later, I needed to hang this siding that has been sitting. Although it was stored under a tarp, it was covered with dirt, leaves, and bug droppings. I spoke with Kim in the Peachtree City, Home Depot paint department and she highly recommended JoMax. I am SO VERY GLAD she recommended it! I laid the siding out on my driveway, mixed it in a sprayer according to the instructions, sprayed the siding down, lightly brushed it with a soft broom, and hosed it off. WOW, it looked brand new! As you can see from the pictures, this stuff works… and works well! I highly recommend this product to clean your house. Thanks again Kim!

          Literally Amazed
          This product was very simple to mix and use. I didn't have to scrub at all. I managed to get all 4 sides of my home done with one bottle. I've got a 2-story, 2700 sq. ft. house with cement board siding on the upper half. If you have a similar size, just get a 5-gallon container and mix the whole amount at once. Also, don't buy concentrated bleach to mix it with, or you'll have to de-concentrate it to get the mixture right. I did notice some stress on the grass at the base of the wall, but it doesn't seem to be severely affected. Spray lots of water and the effects should be minimized.

          Great Stuff
          After A LOT of internet "research", I discovered Jomax. Research said to mix it stronger than the directions state. I used 2 cups of Jomax, 3 cups of bleach and the rest water (1 gallon mix). I would suggest using the manufacture's recipe, first. If it fails, go my route. Initially, the intention was to only clean the gutters, but, naturally, some of the spray got on our vinyl siding. The results were so good, about 75% of the vinyl was cleaned too. In 1.5 hours, Jomax, bleach and water cleaned the back of our ranch home, 65' of vinyl and gutters. Again, all of the gutters and 75% of the vinyl (1600 sq ft ranch) was "spit shinned", with a bit of time. Only 1 gallon of Jomax was needed. A picture is worth a thousand words!

          Works on brick!!
          So the brick around my patio gets really nasty with tree droppings and mold. A power washer alone does not take this stuff off. But I used this Jomax stuff, mixed it with the bleach and water and let it sit for 5 minutes and the nasty black stuff comes right off. Mind you I'm using a pressure washer but I've pressure washed before without Jomax and was unable to get everything off. I'm using a 2700 psi with a 25 deg tip. Hopefully the pictures come through. You can see on the right side by the stairs where I stopped. I'm impressed with this stuff, ps it goes a really long way. Makes 20 gallons which is a TON!!

            did not seem to work as well as in the past...it used to exhibit an exothermic reaction when mixed with chlorine. I applied it as directed 3 times; and will still have to power wash the bricks. It was just a mild case of over the winter mold mildew on a North wall.......not worth the money

            Yes Jomax worked as promised when used as instructions provide. Need to apply two or three time to clear all molds. Only other comment I have is to use fresh Clorox bleach not six month or year old. Cleaning will go much faster. Yes I will use again
