Who freakin' knew? Not us apparently. My hubby ran to Lowe's the other night and they were out of salt. One of the employees suggested water softener salt and the hubby was skeptical, but the employee pointed out that their customers swore by it. So he bought a bag.
Yes, it works. It works very well and it is $5 a bag and pet safe. There are detractors though saying ti can destroy concrete, so here is a link to that for your own information on Cargill's page. It is way down, 23rd question to be exact. Still, if you run out of rock salt and your store has run out of rock salt, water softener salt is a pretty nice back up plan until you can get hold of pet safe rock salt again.
