Not to be argumentative, but to learn . . .
I noticed the HD SDS sheet shows its 94% Calcium Chloride. Wondered what the balance of ingredients were.
Found on the Tractor Supply website, under the 50# bag version of the same product, a question about what was in it. Response says
“This contains 94% pure Calcium Chloride as well as Sodium Chloride, Magnesium Chloride, and Calcium Magnesium Acetate.”
For anyone wondering, I called Meherrin (maker if the product I bought) and talked to (I think) the owner. She stated their product has lime in it and it, among other ingredients, would create issues.
I need 45# of the stuff, so just trying to save a buck or two.
