Wet & ForgetMoss, Mold, Mildew, & Algae Stain Remover Multi-Surface Outdoor Cleaner Concentrate, Original, 64 Fluid Ounces (2 Pack)

I've lived in a new Southwest Florida neighborhood for 4 years. We all have paver driveways, sidewalks, walkways & patios. At my house, the front of the house faces west. Therefore, the majority of my drive is in the shade until mid afternoon. This gives mildew time to grow. Lots of my neighbors are paying to have theirs sealed or pressure washed.The first couple years, I'd drag the pressure washer out at least 2 to 3 times a year. It's a lot of work...and very messy. I'd come back in the house covered with sand and dirt. One day I was at a local ACE hardware store and this caught my eye. I asked one of the "Helpful hardware folks" and he swore by it using it at his house. So I gave it a try over a year ago and I'm hear to tell you, This Stuff Works! Ok, this is NOT bleach. It won't remove the dark spots immediately. As I understand, it's activated by rain? But over a period of a couple months, you'll notice a drastic improvement. So you might want to clean the bad spots before you treat it. Mine's held up quite nicely for a year now and gives me a chuckle when I see my next door neighbor pressure washing AGAIN! I'll probably buy another bottle this summer and retreat some areas.

This is a great product. We use it inside and out. Inside, we spray the shower stall to get rid of mildew when it shows up. Outside we use it on walkways and retaining walls. Great product.

It works very well for cleaning my roof .

Seems to be working well. It would be nice if we would get some rain through to help with the process. It's so much easier to use than climbing up on the roof.

This cleaner is easy to apply with a backpack sprayer. It does not have strong chemical odors which is a plus. It really cleaned our concrete pavers on our patios and driveway really well last year so we got it again. Really like that it does not contain harsh bleaches or dangerous chemicals.

Takes all mold and mildew off works amazing.

My mistake. I received two half gallons for the price to two gallons.

My husband and I swear by Wet & Forget it. Excellent product. We thought we were ordering 2 gallons for the price, (my bad for not reading closer). It is 2 half gallons and I would not pay that again because it is a lot cheaper at other stores. There are no returns so we were stuck with it. Please read carefully!!
