What is the pH?

Sounds like a bunch of salt?

let them pour it on the office plants.. and prove it to you ...

look at the label of winter sidewalk salt/chemicals... i am pretty sure its calcium chloride and magnesium chloride .... and sodium chloride is table salt.. if i recall high school chemistry .....

just cuz its free.. doesnt mean it good ... ken

PS: yikes.. i was right .... check the link and list of chemicals ....
