Used it last year and wanted more for this year for other cement surfaces. It works slowly , but it is better than Power Washing and lasts over a year. Don't make it stronger than 4:1 ratio (recommended is 5:1)

It worked great, but my bricks were slimy black to start with and I wanted to give them another treatment. That is why I bought some of my own product. I would recommend this if you have time to "wet and forget". It does take 6 months to fade the mold.

I have used it on the north side of three homes (two in mildewy, moldy Florida), on driveways, on shutters, on decks. On some surfaces it has worked immediately (metal shutters) while on other surfaces it might take a few weeks to completely destroy the algae/mildew. Amazing product.

Rated 5 out of 5 by from It does what it says! Used it on my summer home garage aluminum siding whichwas heavily mildewed. Came back two weeks later presto no mildew. Used it on my primary home's vinyl siding and sidewalks. Within a week siding was clean. Noticeable difference on sidewalk. Also used it on my wood deck and within a few days all the algae was gone

I was skeptical that this product would remove deep and not-so-deep moss/algae stains on my 23-year old vinyl siding but gave it a try. WOW! After mixing as directed and liberally applying to our house's (vertical) vinyl siding last week using a pressure sprayer nearly all moss and algae was gone following last night's rain. I only used a small amount of the 1-gallon mixture to cover a large area of siding so have a lot left over and will reapply to those few small spots where a light moss residue remains. I hope this product has a long shelf life because a little bit goes a long way at least on vinyl siding. My concern about this product leaving a residue or stain on the siding that would show where the product was / wasn't applied appears unfounded as I couldn't see a difference in the siding's color or appearance. There are a few more areas on the house's siding that need this product but are up high and require an extension ladder. Now that this product has proven itself I will reapply to the small spots on lower wall and then apply to higher spots.

This product worked great but I suggest you clean the vinyl siding first with bleach water...otherwise it takes a longer time to get the mildew off; in other words it takes more applications.
