bath salt hardness prevention

[Galavanting Gifts]

I was just thinking about bath salts and how to prevent them from going hard over time.

Any experiences of what/what not to do?

some use dendritic salts in the mix, but I've not found that to work. I think your best bet is to first let the mix dry completely and then an air tight package because they harden up from water being attracted and then evaporating.
