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.

The most effective product. It works

[This review was collected as part of a promotion.] Just like the name says...wet and forget it. I have no need for a pressure washer for my building maintenance as this does the job. I sprayed it on my roof and driveway and two days later after it rain everything was clean as new

Wet & forget

[This review was collected as part of a promotion.] This product is actually great! Something I didn’t think I needed but now after using it I’ll be a forever user. It gets rid of the mold and mildew that nobody wants. But the thing is that it’s not just that but also moss and algae that grows over time with weather. Easy to use just connect it to the hose and spray as needed. It’s easy to use and it works wonders!

Works like a charm.

[This review was collected as part of a promotion.] Instructions are easy to follow. Removes dirt, rust debris’s on the wall and leaves it looking clean fresh. Dries easily and makes it looking like you just paint it. What I like about this product is it definitely live up to its name, set and forget and it last a Iong time before having to reapply again. I have been a fun of this product for a long time and I can tell you that it works, even on boat and inside bathrooms.

Makes outdoor cleaning so quick and easy.

[This review was collected as part of a promotion.] I am all about outdoor cleaning at the moment so I was excited to try the Wet and Forget Outdoor Max with Xtreme Reach End Hose. I really want to invest in items that makes my outdoor cleaning easier and so far this has been great. Attaching it to the hose was a breeze. What surprised me most though was how well it worked with minimal effort. No scrubbing, no pressure washer, just spray it on and let it go. Over the next few days I saw buildup ...

Very easy to use

[This review was collected as part of a promotion.] This cleaner is so easy to use and is very effective. You hook it to the hose and turn the water on and squeeze the trigger and point at where you want to clean. It works great for mildew or dirt

Wow!

[This review was collected as part of a promotion.] I didn’t know this existed but I needed it for one side of my house that didn’t get sun. There was mold or mildew on the brick. This worked well and then I did a little scrubbing. No weird smell. A lot came in the bottle to do the job.

Great product!

[This review was collected as part of a promotion.] This wet and forget xtreme spray is great! These pictures are before and after only after one use! The design of the bottle makes it super easy to attach to your water hose and you can adjust the water! It does not take much; one spray down and we got good results! I recommend!

Easy to use

[This review was collected as part of a promotion.] Great spray works perfect, it leaves a nice clean smell behind and it’s an easy way to get rid of outdoor mold, and keep it from returning for a year or more. Which is helpful for outdoor areas that don’t get that much sun.

So far so good

[This review was collected as part of a promotion.] I just got this and used it around the house on the wall. So far it does not leave any traces and no smell which is good. I will see how well it protects the concrete after couple months. Ill update the review.

Easy to use

[This review was collected as part of a promotion.] Perfect to get rid of mildew. It’s easy to use. Also easy to attach to a water hose that makes it so convenient. The instructions are very clear. I can totally see a big difference.

Worth the try

[This review was collected as part of a promotion.] It did what it needed to, as far as getting all of the green stuff off the exterior, however now everything is just tinted white, almost like the algae was just bleached. Other than that, super easy to use. I wish there was an easier way to start and stop the water!
