Works great on painted wood siding and brick!
Used this product on a house with painted wood siding and it worked like a charm. Initially I purchased 3 gallons and those went rather quickly as I was mixing according to directions (1:1), however I found that on areas where staining isn't too severe I was able to mix 1 part concentrate to 3 parts water and let soak a bit longer which gave me more longevity out of the product. On the tougher sections I also purchased a long handled scrub brush with a removable head which made the tight corners on the brick entryway a breeze. the brush can be found here: https://www.homedepot.com/p/Quickie-Professional-Pool-and-Deck-Scrub-Brush-With-Handle-2408ZQK/202843359?MERCH=REC-_-searchViewed-_-NA-_-202843359-_-N& I was able to wash the entirety of my 2 story house with about 8 gallons in just about 8 hours or so. Will absolutely be using this again when its time to get the exterior of my house clean again.

      Save Your Money
      I used this product on some outside picnic tables and it did not remove the black mold or stains from the wood, even though I let it soak and rinsed it with water pressurized to 160 psi. I have to clean the tables with a stiff metal brush to get the mold and grunge off. Bleach and water, with a small amount of dish detergent, would have worked as well, so save your money.

        Amazing product…works as described!!!
        This product works AMAZING I haven’t cleaned the siding on my house in over 15 years. This producted worked as described, it even left the siding with a shine that I havent seen in years. My house is 2 stories and there was no way for me to scrub the dirt with a brush. I applied the solution and rinsed as instructed and the dirt came off instantly. I purchase the 30 Seconds 64 oz. Outdoor Ready-To-Spray Cleaner and connected it to my hose and I used the 2.5 Gal to refill the bottle. I took a chance with this product dispute the negative feedback and I am so happy I did. Everyone gave me an estimate for $1000 to power wash my house and for $100 bucks I cleaned the entire house.

          First time use, doesn’t go very far
          I bought the hose end spray bottle because it was the smallest amount my Home Depot had. I used it on concrete and the 30 second claim does not apply. The bottle says to keep it wet for 15 minutes. You end up using a lot of product. I cleaned an area of 6x15 feet and had very little left. I also scrubbed the area before rinsing. It is very sudsy and needs a lot of rinsing. Even though it doesn’t go far, I would use it again.

            This stuff does exactly what it says. I really think it works better than the JoMax I used last year.

            Excellent on Vinyl Siding
            This is great cleaner for vinyl siding. It will spray to the top of the second floor with ease. This bottle is just about enough for both ends of our cape. Will need to buy more for the front and back. Can not believe this works so well with zero scrubbing! Awesome!

                GONE in 45 seconds
                I had used this item before and it did a great job when applied with my backpack sprayer. BUT WAIT....I saw THE HUGE display of this product as I walked in my HD. Sprayer and refill SO convenient right! GREAT! A HOSE END SPRAYER. I set out to clean my very small painted wood deck (7x10) and 14 steps. It took longer to attach and set up the spray area than the spray bottle contents lasted. The bottle was empty before I got to the bottom of the steps. I guess what got me upset was when I went to refill the sprayer and RE-READ the instructions... NOT REFILLABLE. I just feel taken by the HD. I may have bought TWO sprayers if I had read about SINGLE USE. The stuff did clean the deck, BUT the product was GONE in SECONDS
