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.

Easy to apply, starts cleaning within a few days. Don’t expect immediate improvement. However it is clearing up quite well. Hope it will last for a while as it states.
Good, not great
Easy to apply, but didn’t get rid of green algae on siding
Shingle cleaner
Would RecommendEasy to apply shingle cleaner. Took a lot of dirt and grime off shingles without damaging them. Highly recommend.

Wet & Forget does a great job!
[This review was collected as part of a promotion.] We had some awful mildew stains on our siding. Sprayed Wet & Forget on it, then let us do its job. It made such a huge difference! The smell isn’t too overpowering and it dried fairly quickly. Overall, we were pleased with it and ended up buying more to use at our business!

This outdoor cleaner does a good job overall. I used it on my roof to remove algae. It’s easy to apply, and I like that a little goes a long way since it’s concentrated. The only reason I’m giving it four stars instead of five is the price, it’s a bit expensive for what it is. It works well and delivers results, but I wish it were more affordable. Still a solid product if you’re looking for an effective outdoor cleaner.

Was not worth the money.
Would Not RecommendI used this on siding to remove a mild case of mold. It did nothing to address this very mild mold issue.

Does a great job!
Would RecommendLove this product. We get a lot of algae and mildew forming on the shady side of our house. A container of this will treat our siding and the shed out back. In a week the growths have faded and takes over a year to come back.

Complicated and should be one star
[This review was collected as part of a promotion.] I received this and after looking at the instructions, it seems complicated to me. Wet the grass so it doesn’t kill the grass before using? I honestly haven’t tried it yet and not sure that I will.

Didn't work
Would Not RecommendI was trying to remove the mildew on our propane tank. Mixed as stated, sprayed it liberally and waited. After several weeks and some rain storms, it did nothing. Manufacturer keeps saying it takes time, but are we talking weeks, months, years, decades???
Easy to use.
Would RecommendVery good driveway cleaner.
