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.Date published: 2016-07-22Rated 1 out of 5 by Bob73 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!Date published: 2015-09-21Rated 5 out of 5 by Anonymous from great product Goes on easily and really works!Date published: 2014-05-28Rated 5 out of 5 by Anonymous 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...Date published: 2014-04-10Rated 5 out of 5 by Anonymous 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.Date published: 2010-03-18Rated 4 out of 5 by Anonymous 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.Date published: 2009-09-22Rated 5 out of 5 by Anonymous 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.Date published: 2007-09-11

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?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.Date published: 2016-09-30

Applications for Safer® Brand Moss and Algae Killer and Surface Cleaner, Ready-to-Use
For Structural Applications:
For best results, moisten area to be treated with fresh water before applying product. Spray area at a rate of approximately 1 gallon per 100 sq ft of overgrown surface. Avoid spraying when precipitation is expected. Spray affected area to wet thoroughly. Treated mosses, algae, lichens, and liverworts discolor quickly and will dry and slough off naturally, making physical removal unnecessary. Discoloration of treated mosses, algae, lichens, and liverworts take longer under cool conditions.
For Growing Containers and Hardened Bark of Trees:
Spray affected area to wet thoroughly. Use on ornamental trees only. DO NOT APPLY Safer® Brand Moss and Algae Killer and Surface Cleaner 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. 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. Safer® Brand Moss and Algae Killer and Surface Cleaner may leave white residue on cement, brick or dark-colored shingles. This residue may be removed with vinegar.
STORAGE AND DISPOSAL:
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.
