Wet & ForgetMildew Removal, 48 Fluid Ounces, Blue, Fl Oz

I’ve used Wet and Forget for pump for years and love it. We wanted the hose connection Extreme for the hose connection. This is more concentrated than the wet and forget that you mix 1:5 and the hose makes large and hard to reach areas easier.The main positive is:1. You can do large area with fan nozzle and far distance with other nozzle.2. Like that you see foam when on (this confirms that it’s on).3. Like that you can turn on water without product.4. Like that it didn’t leak around hose connectorThe main negatives:5. It didn’t cover 2000 sq feet. I contacted company and they said coverage is only 750-1000 square feet if you are using on a porous surface. We used on bluestone and vinyl siding. Although Bluestone is porous, we didn't spray extra due to fast absorption. Our overall coverage was close to 1000-1200 sf.6. Spray and distance nozzle kept coming off. By the time I was able to turn off sprayer and put nozzle back on, product was misdirected and wasted.7. Difficult to turn off for nozzle or location change. While struggling you are misdirecting and wasting product. Note: I have used other products with hose spray applicator that made on and off easy. I sent a photo of one to the manufacturer.I’m hoping company can make improvements to the applicator. While description states up to 2000 sf, product should indicate coverage will be 750-1000 sf when used on a porous surface (e.g.,brick, driveway, roof, paver, etc). I'm also hoping that I will get the same good result over time as I normally get with the regular Wet and Forget. Since results not immediate, time will tell.

I am amending my review after a few calls to the customer service.The nozzle was no good. I connected the nozzle with the hose and opened the water faucet. Water spurted out all over. There is no instruction sheet. Not knowing what to think of I thought maybe the string tying the aiming tip should be cut to allow the nozzle to come out fully; maybe there is something sealing the water. No! The nozzle simply flies out as soon as I turned the water on. I called the customer service. After a long weekend I finally was able to talk to the customer service. Of course she understood! She immediately shipped a replacement nozzles out to me. This 4 star is for the customer service. I just applied the washer. I am waiting to see the result.

I've used this product on decks, roofs and concrete driveways. The sprayer blew apart and will not work. My first bottle did the job for a few years. but this year when I tried, the nozzle shot out of the front and water sprayed from all the joints of the sprayer. I bought another one and again it blew apart. I was drenched with whatever the solution is. I will call customer service and the other reviewers did and see if they can fix this frequent issue. Or I'll try the hack I just saw on Youtube

Fortunately I ordered 2 bottles. One leaked really bad; half the product was in the plastic bag. Amazon accepts no responsibility! Wet It is shipping a replacement. I had no problem with the sprayer, but I couldn’t get 30 feet out of it; probably 15. I did watch a utube video that suggested using a shut off on the end of the hose with quick connect attachments and that worked really well. I have to see how well it works in time, but I’m hopeful. Not happy with Amazon!Second day, got better range out of the sprayer. Seems like it works better when it isn’t full,Got really good range with the stream noodle versus fan

I usually buy the wet and forget concentrate and use a pump sprayer for where I can reach. I needed to do the second floor of the north side of the house and this eliminated having to use a high ladder while trying to hold onto the ladder the pump container and aim the sprayer.Worked out perfect and got better with each rain.
