Moss on outdoor carpet

Ok, I cleaned an outdoor patio this morning. Moss on the carpet. Even with lots of agitation, there is still moss clinging to the fibers. Now, here are my thoughts about this job.

Perhaps the hot water was able to kill the moss and in a few weeks, the "roots" will release from the fibers and I can reclean it and get the rest off, BUT, there will still be residual "staining" of the carpet.

Another thought, and one that really appeals to me, is to spray the outdoor carpet with Roundup. It will kill the moss for sure. A few weeks later, I'll reclean, and the rest will detach.

Now, keep in mind, this carpet is now a 1000% better than it was before I started this morning, however, I want this stuff DEAD and gone.

Any other reasonable ideas?

BTW, I'm sure the Roundup won't hurt the carpet, but it sure as heck will put the hurts to the moss.

Roundup is a salt, that become inert with soil contact. Much of our food supply is grown in soil where Rounup has been used. I'd have no worries putting it down, outside, on an olefin carpet. I know it will kill the moss. Not so sure about peroxide based cleaners.

I have considered using the RU, then coming back a few weeks later with OSR and a good rinsing.

I was thinking of bleach as well, not sure I wanted to go that route as it's tough to neutralize. But, doable. Makes more sense to me than a peroxide based cleaner.

I gotta kill this stuff. DEAD.

Isn't bleach a poison as well? Most of what we use are "poisons".

You'll use Roundup in your yard to kill weeds, but on the outside patio, with a rinse, you wouldn't consider it?

Will the peroxide kill the moss so it can be removed? The "roots" of the moss are intertwined with the fibers, until it's dead, it will not degrade and be removeable.

I'll consider the OSR, but some folks need to open their minds.

I was gonna use a Quat on it, but thats a poison as well........

Polyethoxylated tallow amine (POEA) is a surfactant that enhances the activity of herbicides. It improves the solubility of many common herbicides in organic solvents[1], increasing their penetration of the waxy surfaces of plants. It may also interfere with the function of tadpole gills[2][citation needed]. This surfactant is not regulated under environmental laws because it is not considered an active ingredient in the herbicide.


Please keep in mind, such surfactants are also used in lawn sprays to help hold the active chemicals, like 2,4,D and Roundup on the plants so it kills.

I'd guess Chemlawn and the like use similar substances on your yards and you don't even know it.
Farmers use these chemicals on crops all the time. After a period, the crops are harvested and fed to the animals we eat, or milk.

I have a pretty good base of knowledge and usage of Roundup in a hobby of mine. I'd trust it in this particular application.

Guess its tough for city slickers to understand
