Any kind of table salt (no MSG or other non-NaCl flavor substances).

We’ve used brown rock salts in Thailand and flakey salts from fancy restaurants. It all works. However, larger grained salt may require the user to mix more salt into the salt brine bottle. This is also true for rock salt.

Simply remember: If you get a low salt light, just add more salt!
