Rated 5.0 out of 5.0 by MO Works Very Well--Much Better than Granules
This product works very well with a hose-end sprayer. It is inexpensive, very easy to apply, and kills the moss within hours.
I use this product in the spring and in the fall when my cool season grass is actively growing. Killing the moss gives the grass (fine fescue in the shade) a chance to grow and spread. The moss does return, but the grass has been filling in quite nicely over the past couple of years.
There is no point to killing the moss in the summer or winter when the grass cannot take advantage.
Granular moss killer is easier to spread, but it does not work nearly as well, and the dust is terrible even wearing a mask.

Rated 4.0 out of 5.0 by KP One of the few products that kills moss
Moss Out for lawns is actually the only product I've found that will kill moss growing in the lawn. A gallon only treats 2,000 square feet, and it takes at least 3 applications during the growing and watering season, so it can get expensive. You can spray the diluted product directly on the moss and it will turn it black almost immediately. I think the better option is to rake the moss up and dispose of it and then spray the bare soil to kill what remains and prevent new growth so grass can reestablish itself or you can seed. Moss growing means there are soil issues. In my case it's heavy clay and dense shade. Whatever is causing you issue that is cultivating the growth of moss will not be corrected by applying Moss out. You will have to commit to a regiment of care to prevent the moss to infinity and beyond.

Great Product, too bad it can only be purchased online in my area. It should be stocked on store shelves. Works better than granules.

Works on moss fast and changes its color, so u can go back later n get what u missed.
Be sure to mix over grass so not 2 stain concrete. Will stain hands 2 slightly, so good to wear gloves. The iron is good 4 grass and plants 2.

Rated 2.0 out of 5.0 by bummed Somewhat disappointed
The product stained the surfaces that I sprayed with Moss Out. Everything I sprayed has a brown stain after it dried. Some of the areas (stones around my home) still have moss after a week. I have found that using plain old baking soda does a better job. I am not sure which is worse, moss on my rocks, sidewalks, and painted exterior basement walls or brown stain.

Rated 1.0 out of 5.0 by MrMagoo Stains concrete badly
I purchased this product, applied to the moss and had a few small accidental spills on the sidewalk, which I hosed down immediately. They didn't come off the concrete. I contacted the company to ask them how to clean this and was told their product "did NOT stain concrete but to use iron out to remove the stains", which is contradictory. I followed up by sending them pictures of the stains as well as letting them know the iron out had made the issue worse. I received a reply from the company projecting their unprofessionalism and the tone of their email on to me, as well as telling me that the bottle and website never claimed to not stain. I am very dissatisfied with this product, the company's response and do NOT recommend it. It hasn't even killed the moss to which is was applied 5 days ago.

Moss turns black within minutes and dies completely in a week or so. So far it has not come back.

Had to pretty much double the dose to get fairly good results.
