BioAdvanced2-in-1 Moss and Algae Killer for Lawns, Roofs, Patios, Decks, Roof Moss Killer, Deck Cleaner and Mildew Remover, 32 oz

KILLED my moss on carpeted patio! Our back porch is a screened in porch and in one section moss always grows and I've had a terrible time trying to remove it. We've tried power washing it, bleach etc. We thought to give this a try and it worked over night. Attached to hose sprayed the area and within a day or so we noticed the moss slowly fading and dying away and has not come back. It does not affect the carpeted area either, there is concrete below the carpet and there is no damage there either. We did this on another area that is not covered and same thing, took the moss away immediately and has not come back! Highly impressed with this purchase!

Works perfect

Very disappointed in the effectiveness of this product. I'd give it zero stars if I could. Since using this product, what had started as a small 'maintenance' problem to tackled a few areas that more shade has blossomed into a major one. The picture shows the roof I treated 2 weeks after the fact. It is now an order of magnitude worese For years, I've used bleach and water, but thought I'd try something less harsh. I'm pretty sure that the ingredients fertilized my moss, not kill. I will not be using this again for this purpose.

Used on my cement patio. Also on my plastic white chairs. Worked great

I am wondering why the product was not sealed it made a mess i gave 3 stars because it spilled out

Why did you pick this product vs others?:Can never go wrong with this. I spray it on the lawn, patio, side of house etc. Turns moss/algae black and stops from coming back. Easy to use.

Basically ineffective. This didn’t seem to do much compared to 30 Seconds’ outdoor cleaner, which costs half as much as (by volume), so I’ll stick with that brand from now on.

It worked
