Safer® Brand Moss & Algae Killer & Surface Cleaner Concentrate 32oz Hose-End Sprayer is rated 4.3 out of 5 by 7.
Rated 5 out of 5 by from Works Very Well Many cleaning products adversely affect metal around a window, so this spray is effective and safe. The only thing I'd recommend adding is the spray setting mix ratio on the RTU packages because I have places where I need more range and switch to a hose sprayer with a tighter nozzle.

Rated 1 out of 5 by from Worthless I first tried this product last year to try to get rid of the moss on my roof. It did no no good at all. I thought that maybe I had done something wrong the first time so I tried it again yesterday being careful to follow the directions. The directions say that the moss will start to turn brown after ten minutes--in fact its been 24 hours and the moss is as bright green as it was before I sprayed . . . and the lichens are a nice healthy greenish white color. This product is a total waste of time and money. The photos are 24 hours AFTER application of the product!

Rated 5 out of 5 by from Don't make the mistake I did! I ordered one bottle of this product with the hose sprayer and several of the spray bottles without the hose sprayer, thinking I could just attach the hose sprayer to each of those bottles. The original bottle did an unbelievably good job but the subsequent bottles did not. It didn't dawn on me until much later that there is a much weaker formula in the regular spray bottles so I had managed to dilute them with the hose attachment and it didn't work. I have several spray bottles left over now...

Rated 5 out of 5 by from Simply the best There is no other product that works as well as this. I've tried them all on some serious moss build up on my roof and Safer® Brand works to eliminate it safely.  Got my neighbors using it now.

Rated 4 out of 5 by from Review Posted on Amazon.com I have a moss problem on my brick walks, as well as other places around the house. I used this, and it does a good job of killing about 85 per cent of the moss. The hose end sprayer works great, but I would just warn any users that the fatty substance that comprises this product is an eye irritant, so use protection. Repeat sprayings are necessary, but this is far safer than using some dangerous chemical--it's basically strong soap.

Rated 5 out of 5 by from Review Posted on Amazon.com With a 10 minute spray the moss on the shady side of my house (cedar shingles) was completely gone/dead/faded in 3 days; better yet, four months later (late spring through summer) there are no signs of the moss coming back. It's great when something really works as advertised.

Is this safe for wildlife? I have a lot of birds and squirrels in my yard and on my roof. And, do you have to apply in dry weather?

Upon spraying a roof for algae and moss, if the grass below has moss, will it kill the moss in the yard which I want to save if it is watered down immediately and diluted?

Asked by: Galen
As this product is a moss killer, we would not recommend spraying near or allowing any runoff to come in contact with moss that is looking to be saved or protected.

Applications for Safer® Brand Moss and Algae Killer and Surface Cleaner, Hose Sprayer

For Structural Applications:

Apply mixed spray at the rate of approximately 1 gallon per 100 square feet. For best results, moisten area to be treated with fresh water before applying product. Spray area until thoroughly wet. Treated mosses, algae, lichens, and liverworts will discolor quickly. For best results, leave spray on area for 10 minutes following application, then scrub using a push broom or similar type broom, then hose off with fresh water.

For Growing Containers and Hardened Bark of Trees:

Spray affected area to wet thoroughly. Use on ornamental trees only. DO NOT APPLY to fruit trees, foliage or green bark of conifers or broad leaf plants.

For Mosses in Lawns and Turf:

For best results, moisten area to be treated with fresh water before applying product. Avoid spraying when precipitation is expected. Spray affected area thoroughly at the rate of approximately 1 gallon per 50 square feet. After 30 minutes, rinse sprayed areas lightly with clean water, then withhold water for two days. Do not treat turf when temperature exceeds 85°F.

PERSISTENT MOSS GROWTH ON LAWNS is symptomatic of too much shade, acid soil, and poor drainage. If several sprayings do not reduce moss problem it may be necessary to reduce shade, aerate and lime the soil.

NOTE: Treated areas may be temporarily slippery. Product may leave white residue on cement, brick or dark-colored shingles. This residue may be removed with vinegar.

Storage and Disposal of Safer® Brand Moss and Algae Killer and Surface Cleaner, Hose Sprayer:

Storage: Store at room temperature, in original container only, out of reach of children and animals. Keep from freezing. Disposal: Securely wrap original container in several layers of newspaper and discard in trash.
