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.

Will try again, since I had some tough stains

[This review was collected as part of a promotion.] Wet and forget Extreme reach hose was okay. I won’t give up on it yet, as the driveway needed a lot of help so it’s better than it was and I will try it again.

Hopefully it’s good

[This review was collected as part of a promotion.] I received this product from Wet & Forget for free in exchange for this review. My area is very dry so the stain remover is not of that much use. But if you live in moist area, it’s easy to use. Connect hose to the tip and spray. I sprayed a little bit at the corner of my garage. Hopefully it will help.

Does what it claims

[This review was collected as part of a promotion.] Really likes this product for cleaning the residue on my cement from winter. Overall coverage was great as well. It does have a strong odor but goes away. I believe this product was definitely effective and does what it claims.

New favorite outside cleaner!

[This review was collected as part of a promotion.] I used this on one of the junk cars we have, that hasn't been washed in way too many YEARS, and this stuff actually worked! You can see the before and after photos for proof! I can actually see my reflection in one pic! Lol. This is going to be my new favorite/easy cleaning method! The nozzle worked great and has a great reach! It is very powerful which I loved and wasn't expecting, bcuz our hose isn't the strongest. Yet this worked beautifully...

Harsh chemicals

[This review was collected as part of a promotion.] I sprayed this on a low spot of my driveway that tends to stay shaded throughout the day. Being a spot that collects water and isn't in direct sunlight means it gets mildew. It attaches to my hose easily and sprays evenly. 2 days later the mildew was a rusty color leading me to believe it was dying off. It was not removed though like the instructions led me to believe would happen. I am rather concerned with the safety warnings on the bottle t...

Really works!

[This review was collected as part of a promotion.] This is super easy to use and very convenient. It got the mold and mildew out of the walkway in our backyard. It attaches super easily and worked like a dream

Removed some of my problem

[This review was collected as part of a promotion.] This product removed about 50% of the stain that I had on my concrete. I read that it also works over time so we'll see if anymore gets removed. It was easy to use as long as you have a hose to attach to it. It did say to use protective gear like eye wear and gloves so that is something to take note of. I would use this again and try it on a different surface such as wood.

Unfortunately it does not clean as advertised

[This review was collected as part of a promotion.] Not very impressed. I chose a section of my fence that wasn't even the dirtiest, and this product couldn't handle removing all of that, so if used on something extremely dirty or mildew I suspect the purchaser would be even more disappointed. I gave it 3 stars for ease of use. Just hook up to hose, turn on water, flip small slide to on position and the product is dispensing.

Great Maintenance Product!

[This review was collected as part of a promotion.] This product hooks right up to the garden hose. It has a strong spray that reaches up to 30 feet high. It covers large areas fast. You literally spray it and walk away. It works on siding, patios, concrete and fences. There is no bleach and it’s non acidic. This will not damage surfaces like harsher cleaners can. I would use it for yearly maintenance, not sure if I would use for heavy years- old stains.

Easy to Use

[This review was collected as part of a promotion.] I was selected to try Wet & Forget Outdoors Extreme Reach complimentary as part of a try-free program. My husband and I waited for the right day when it wasn't going to rain and used it on our roof's solar panels to remove pollen and mildew buildup. It worked well, was easy to use, and sprays far. We plan to use it every year from now on because it gives the clean you need without the hard work. This is a powerful, easy way to get panels cleane...

Mildew and stain remover

[This review was collected as part of a promotion.] The Wet and Forget Xtreme Reach Remover was used on my drive way. You can see the before and after, it is a day apart but I didn’t see too much of a difference. The spray is super easy to use though, and it’s very soapy, almost like if you washed your car. You didn’t have to rinse anything which was also nice and it didn’t leave any kind of residue. Overall, I don’t think it worked great on my driveway but maybe next time I’ll try my fence!

Works like magic!

[This review was collected as part of a promotion.] I received this Wet & Forget product in exchange for my honest review. It worked amazingly well! I have algae growing on top of and between many grooves of my multi-colored concrete. My hose attached easily to the bottle and sprayed down the area quickly. I forgot to wear gloves, but didn’t have a bad reaction (whew). The next day more than half of the algae was gone. The magic continued over several days. The product smells nice (sort of like...

Best ever

[This review was collected as part of a promotion.] I used it in combination with my pressure washer and it worked like magic! Great for siding and easy to spray. Low odor and doesn’t smell toxic at all.

Great product

[This review was collected as part of a promotion.] So easy to use, it’s easy to attach to the house and spray onto your roof. A little goes a long way! I highly recommend this in order to get rid of moss and other things you don’t want on your roof!

A little awkward to use at first

[This review was collected as part of a promotion.] I received this product free in exchange for my honest review. At first I had a hard time hookinh this up to my hose, but once I got it, it was fine. I found it a little hard to hold/manage because with my hose dragging behind it felt quite heavy. I tested on a small area and while I noticed it looked a bit cleaner after, it wasn’t a shocking before and after I’m more interested to see if it keeps mold/mildrew at bay and will likely be testing ...

Not good at all

[This review was collected as part of a promotion.] Sorry to share that wet and forget was not at all helpful in removing a simple stain on a clay pot outside I shared the before and after pictures which speaks for itself
