Prestone Driveway Heat

[olds350racer]

I have been using Epson salt (magnesium sulfate) as a magnesium additive. In an effort to get away from the sulfate, I would like to use magnesium choride. I have read of many people using Prestone Driveway Heat, but with the recent impurities found in MagFlake... it makes me nervous to use any non-lab grade magnesium chloride. Has anyone heard one way or another regarding the purity of Prestone Driveway Heat?

none that I know of. I have a case of it and will probably continue to use it.

FYI: Driveway heat is on sale at Rite-aid for like $5 a container. I do not know if that price is good or not (I do not use it) but I figured I would let people know since I saw it.

yup, thats a really good price. It usually goes for 8ish

OK I just realized I need to correct myself. Prestone Driveway Heat is Calcium Cloride (not Magnesium Chloride). I'm sure most caught that, but I don't want someone to get bad info from a thread I started.
