? for Randy on Calcium Chloride Flakes

Prestone is made by Dow, so it should be okay. The other product might be safe, but there's no cost-effective way to be sure.
 
I use the prestone brand...its about 90 % pure CaCL2 the rest is salt and a little bit of potassium chloride (less than 1%). Never had any issues with it.
 
I thought I read somewhere that the pelletized form of this included some sort of heavy metal as a binding agent. I is confuzed.
 
I haven't read that anywhere. Do you have a link? Lots of people have used the Prestone product without problems.
