What Customers Are Saying

Customers praise the product for effectively removing mold, mildew, and algae from outdoor surfaces with minimal effort. Most highlight its simplicity—attach to hose and spray—with visible results within days or weeks on siding, roofs, and concrete. The "wet and forget" approach is frequently cited as a major advantage. However, many report nozzle issues including twisting, detaching, or inconsistent spray, with effective range closer to 15-20 feet rather than advertised 30 feet. Some note variable results in shaded areas requiring multiple applications. Despite hardware concerns, most customers consider the cleaning performance worthwhile for routine maintenance.

Love it

[This review was collected as part of a promotion.] Used this product on our pool deck, safe to say it removed all the stains very effectively. It’s easy to hook to the hose, and spray is very nice too. Not a very strong smell, goes on very well.

So Frustrating-So Difficult to Use.

Would Not Recommend

This was one of the most frustrating experiences I have ever had with a product I used to trust. I’ve used Wet and Forget with my pump sprayer multiple times in the past and had no problems. But this time I had to reach some high spots and didn’t want to climb the ladder. So I got the extended reach hose-attaching bottle. The design is trash. First, there’s no direct on/off trigger. It’s a dial-type that ranges from “off” to “water” to “”on.” There is no “click” into each of these positions. I...

Effective !

[This review was collected as part of a promotion.] I used this to get the dirt and algae greenish color off of my porch fence and railings and it did an amazing job. It really brought it back to white white. I was impressed and will do it again in a couple of months. 5 stars !

Spray it

[This review was collected as part of a promotion.] Easy to follow instructions and even easier to use. You just hook it up to a hose, spray it and it works on its own. I deducted a star because I needed to spray it a few times to see real progress but with how simple it is to apply - I did not mind it much. Would definitely use it again.

This is a two person project!

As there is no water control valve on the bottle, have someone turn on the faucet for you once your spraying site is chosen. Product sprays immediately once the faucet is open!

Turned my concrete brown

[This review was collected as part of a promotion.] This product did nothing but make my concrete brown!! It looked worse after the application. My husband even tried a second application the next day but this time scrubbed it with an industrial push broom - no change, still brown. We are going to have to pressure wash the concrete and hope for the brown to go away. Additionally, read the warning label and instructions. I originally planned to use this on my patio near the pool deck. The warning...

It’s a no for us

[This review was collected as part of a promotion.] Well we waited and tried this for a week straight. We did one area waited a day then did it again. Total of 4 times and saw no results. Did exactly how instructions said and it’s a no for us. The smell is a little bit of a chemical smell so if you’re sensitive I wouldn’t use it.
