How to reverse the rock salt that has become powdered salt?

I would assume you can dissolve it in warm water, put a string in it, and it will crystalize again like sugar does? I’m not sure, we need one of our science Jellies.

Why do you have this much rock salt? What purpose was it purchased for? Chemically it should be the same no matter what form it is. I would be taking a nightly bath with a cup of the salt to start. I would also throw it on the ice on my driveway when it snows.

Crush it up and mix it with some water to get it fully dissolved. Then let it sit and the water to evaporate.

I’d use it as is. If it is a hard block I’d hit with a hammer or drop the bag on the ground aafew times to break it up. Don’t throw it away. Use it.

Good ideas @everyone. Is 20 lb a huge amount to buy at one time?

Oh 20lb’s? Just use it as is or make a brine. Are you using it to melt ice on a driveway?

It’s for gripping purposes, until the ice melts,

I just discovered that. I guess ice melt is the better term unless it’s a brand name too.

The salt actually does loosen the ice. If you want grip you can use kitty litter, but it kind of makes a mess.
