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.

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!

Great product!

[This review was collected as part of a promotion.] As you can see there is plenty of space for this to be effective. The white portion of concrete is what I tried so far. Can’t wait to complete the yard so it’s much cleaner. Definitely do not breathe in as it’s chemicals. Easy attachment for your hose for ease of use. Definitely will be a staple especially to clear the floorings

Spray once, stay clean

[This review was collected as part of a promotion.] Wet & Forget Xtreme Reach is super is super easy to use and surprisingly effective.

Clean results in time

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.

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!
