Wet & Forget Outdoor Moss, Mold, Mildew, & Algae Stain Remover Multi-Surface Cleaner, Ready to Use, 64 Ounce

I have been incredibly impressed with this cleaner! I used it on family headstones that were showing age. I do not live close so I’d just take the cleaner with me on occasional visits. Spray it good (in any climate) and let it do its thing over the course of a couple of years. The granite looks almost new now. Thank you for providing such a quality cleaner that’s helped me to honor my loved ones memories! My container is almost empty so I will be ordering more to keep them looking great.

I got this stuff to clean the algae off our outdoor shower. I sprayed it on and it worked its magic and melted off. Not sure how this stuff works, but it was literally spraying it on and letting it do its job. It's super easy to use but it does stink when spraying it, so be cautious of that. Otherwise I would highly reccomend this stuff!

THE CLEANSER WORKS G REAT I NEVER GOT MY EAR PLUGS

This stuff is AMAZING! It literally worked overnight for us! I am in disbelief that we found something to get algae and moss removed without pressure washing or scrubbing! My husband is very pleased and felt it has saved him a lot of time from having to pressure washing! It is literally just like it says…Wet and Forget! Thank you to the creators of this product! I am not one who typically takes the time to do reviews but I could not wait to do this one! I will have to share with my neighbors at the next book club meeting! Lol

Pro: I purchased 3 of these to cover the area that needed to be cleaned of mold, spattered black spots of unknown origin, and green algae on concrete. The trigger was easy to use, no smell, no leakage, big size, and has a trigger spray or stream that my hands were able to use for two hours which was a pleasant surprise because I have arthritis in my fingers and joints. I only used the stream instead of the spray nozzle because it dispensed a larger quantity onto the concrete. The container is attractive, but I found it too heavy to carry for long, even switching hands frequently. I'm shorter in height so I could set it down on the ground sometimes and that helped me finish the job.Con: I didn't see any changes in the appearance of the concrete, but the bottle states it can take anywhere from a month to a year for it to work it's magic. Obviously, there is no way to currently review its' effectiveness at this point! I've given it a 3 star rating for now, but if Amazon lets me, I'll come back to comment on any changes when I see any.

Total garbage. Complete waste of time. The instructions say to wait after application for the mold/mildew to disappear. Without any rain, even the lightest spots on the garage door didn't change at all after two weeks. The instructions glibly state you might have to wait a YEAR for the most stubborn areas to disappear. At this rate, we'll be replacing the door before it might work. What a joke. I should have spent the $19.00 on anything else but this. I wish I could give zero stars but I can.t

Effective, easy to apply, lasts about two yearsI have shared this with 2 neighbors and several friends, all have been impressed.I used it originally on my vinyl siding and then tried it on my fiberglass shingles. It works quickly on the siding and needs more volume and time on shingles.

I actually thought I initially it was horrible and was going to return it but, after 24-36 hours after applying, it worked like a miracle! All my green brick patio mold is completely w. My patio is 15x 20’ and I didn’t even use a full bottle. I highly recommend this product.
