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.

This stuff works

[This review was collected as part of a promotion.] Amazing product. Wet & Forget couldn’t be any easier. Make sure you wear grubby clothes. We used this on a retaining wall that had mildew and moss growing on it. Sprayed it on the problem areas and let it sit. Then we rinsed the areas with the hose and they looked like new.

Don’t need to scrub

[This review was collected as part of a promotion.] I tried this product on my landscape sidewalk, and it was easy to use since I just attached it to the hose and sprayed ever down. I liked that there was no strong bleach smell and didn’t need to scrub. The dark stains took longer but still improved over time. The only downside is that the results are not instant, so it works better if have patient and low effort cleaner.

Great stain remover

[This review was collected as part of a promotion.] This cleanser spray works great on my patio and driveway! Super easy to attach to the hose and cover a large area quickly. It removes stains perfectly. Just spray it on and let it work.

Easy to use and works well!

[This review was collected as part of a promotion.] The Wet & Forget Outdoor Max hose end product was super easy to hook up to my house, point, spray, and use. Simple hook up, then just spray It on and let it do it's thing. Doesn't get much easier than this, and it does a great job cleaning stubborn stains off concrete. Great for spring cleaning before the summer comes!

Wear protection when using!

[This review was collected as part of a promotion.] My husband was waiting for this to try it. You definitely need to be careful spraying this… harmful to eyes, skin, and if you breathe it in, so protect yourselves!!! The container is smaller than I thought, says it’ll cover a whole house… not sure if it will? I have a 2800 square foot house. There is a very mild odor, not sure how long it takes to dry and take effect.

Not good.

Would Not Recommend

Sprayed on areas of house. Didn’t like because it didn’t say it could take weeks or months to clean according to rain washing it off. All I got was strieaks down my windows.
