I bought 2 bottles last year figuring that it would take care of our patio algae.
Ya look at the front label and figure it can be used darn near anywhere. Not necessarily true.
On the back there is a "Peel Here for Precautions" corner. Inside it has all the precautions that one would expect - corrosive, may cause blindness, do not allow skin contact, use PPE,etc. What pissed me off was the last little area that warns that it is "toxic to fish and aquatic invertebrates. Do not allow discharge effluent containing this product in to lakes, streams, ponds . . ", etc. Well crap, I live on a lake!
So needless to say I haven't used it.
And oh, the usages are confusing. It says that you can use it on patio furniture (but not on the cushions or wood frames) but further it says that it can be used on wood decks.
