Seasoning the humidor....in-season

[Bkcloud114]

I don't know what the reverse osmosis does, but don't they use salt to soften water?

I hope this answers your question Shelby..... Salt is used in a water softener, but the sat itself is not added to the water to soften it. The ions are used to clean the beads which hold the ions which create hard water.....
