Wet & Forget Outdoor Stain Remover, Xtreme Reach Hose End Cleaner, 2pk 48oz

I used to spend many hours and usually more than one day cleaning my driveway. Now I just hook this product to my hose, spray evenly on my driveway and sidewalk, and forget about it. It's so easy to use! This product doesn't work right away, so Don't think its defective. It works by combining its chemical properties with nature's: sun, wind and rain. As weeks passes, you'll notice the areas where Wet & Forget was used looking cleaner and cleaner. I buy the package with two bottles. I use one bottle for my driveway and sidewalk, and the other one for my fence.

Love it, perfect for me and my house

This product will wet, but forget getting your house clean. I tried this on the mildew and stains on siding on 2 houses. It was a waste of money, water, and time. It did little to nothing to clean the stain. Don't waste your money. I've attached 2 after treatment photos from the second house. I even used a pressure washer to rinse.

Very satisfied with the results using Wet & Forget on my roof. Had pretty bad stains & some moss starting in shaded areas. Some reviews complain about results. It is NOT an overnight process. It takes time. I've done three applications over the course of a year. Moss is completely gone and stains reduced by 75-85%. Very satisfied & definitely recommend.

Stuff really works, but I had to hire someone to do it for me. It’s toxic and I didn’t want it to spray in my face.

If your life goal is to clean your entire house while holding a beer in one hand and a garden hose in the other, welcome to your new religion.The Setup: Unleashing My Inner GhostbusterThe bottle claims it shoots 30 feet. They are not lying. I hooked this bad boy up to my hose, turned on the tap, and instantly felt like a firefighter saving a suburban neighborhood from the devastating threat of... green porch moss. I sprayed my roof, my siding, my driveway, and accidentally my neighbor's mailbox. Zero scrubbing. Zero ladders. I just stood there like a lazy deity soaking my property.The Drama: The Great Waiting GameHere is the catch: this product requires the patience of a saint. If you apply this expecting a satisfying, TikTok-worthy "before and after" transformation within ten minutes, you will be deeply disappointed.For the first three days, absolutely nothing happened. My house just looked wet. I felt cheated. I stared at the mold. The mold stared back, seemingly mocking my purchase.The Miracle: The Magic of Moving OnThen I forgot about it. Two weeks later, I walked outside, looked up at my siding, and blinked. The green sludge was just... gone. The wind and rain had literally stolen my mold in the dead of night. It is like hiring a tiny, invisible cleaning crew that only works when you aren't looking.The VerdictThe Good: I cleaned my second-story roof without climbing a ladder and facing my impending mortality.The Bad: You have to wait weeks for results. It is the snail mail of home maintenance.The Ugly: If you don't rinse your plants first, it will turn your wife’s prized hostas into crispy, brown sadness. (Ask me how I know).Buy this if you love clean houses but utterly despise physical labor.What specific outdoor surface are you trying to clean with this? If you tell me what kind of organic sludge (moss, mold, algae) you are fighting, I can tell you exactly how long you'll have to stare at it before it disappears!

Update: I'm adding two stars because after the first rain most of the black algae was gone. 2nd rain left my roof lining like new! Impressive. The design is the sprayer remains awful! First. Why are there parts and pieces tossed in the box and tied to the bottle? WTF am I suppose to do with them? The requirement to hold the bottle to turn from off to water to on is an awful design! I probably washed a lot of the product off my roof before I was able to get it turned off. Then, because the design is awful, I found myself holding the hose and nozzle while the bottle sat on the ground. Yep. The nozzle was steadily spraying without the bottle being attached. When it was finally over. Thank goodness it was over, I was soaked. Why? Because even with all gaskets in place, I was only able to get the hose connected right enough one time to stop drips and sprays of water. Functionality is awful. I live in a 1 story ranch and the sprayer had a hard time reaching the peak. Yes. I definitely needed a ladder. I will say that the product did release a lot of dirt from the shingles. Time will tell if it will clean the black mold. It became a little windy as I neared completion so I can tell you it didn't taste too bad and the smell is pleasant

I did a sidewalk that was 25 feet long. I sprayed it pretty heavy before sundown so the sun would not dry it out. The next day the sidewalk was still dirty. Over the next 5 days we received an inch of rain ,but the rain did nothing. I sprayed my driveway and it did not remove the dirt either. I ended using my pressure washer. I was not very satisfied with the product and would not buy it again.
