I use prestone driveway heat,,,I called the mfgr. and they said it is 99% calcium chloride,,,It has been months and so far so good!

I believe Randy says Prestone Driveway Heat is ok.

It's 77-80% calcium chloride like Dowflake. Anyone try this? I can't seem to find 50lbs of Preston around where I live.
