What Customers Are Saying

The product effectively kills moss and algae on various outdoor surfaces, with many customers reporting quick results within hours or days. It is easy to use, just requiring attachment to a hose for spraying. The product is selective, targeting only the moss and algae without harming surrounding plants or grass. However, some customers did not see the expected results, with the moss or algae remaining even after repeated applications. The product's cleaning ability was also criticized by a few users. Additionally, the coverage area per bottle was found to be limited, necessitating multiple purchases for larger areas.

Expensive for the result

Would Not Recommend

For the money I thought it didn’t work as well as I had hoped. Only the very first part of what moss I sprayed actually is gone. The balance is still green.

Use watering can application

Would Recommend

I suggest deluding with water in a watering can and sprinkling on affected area. Using a hose does not kill ground moss on black-top in one application if attached to a hose.

Easy to Use and Effective

Would Recommend

The design of the can is really easy to use. I simply hooked up my hose, moved the lever to "open" and sprayed on the product. Some of the Algae on my storage hut roof came off immediately. Others I let sit and now I have the choice of either letting the rain wash it off or taking a scrub brush. Either way, it's pretty simple and it's effective.

Great product

Would Recommend

This product works. I was initially skeptical but an hour after spraying it on the moss on my walkway, it turned brown. Two days later I was able to sweep almost all the dead moss up.
