Oh no, well i’m sure that’s a part of it too but i think it’s more the source. Our oceans are littered with photodegrading plastic bags and bottles etc (resulting in microplastics), so evaporating that for the salt also leaves you with that. Not sure if there’s even any way to attempt to remove it.

The one i’m getting from onlysalt.co allegedly comes from the peruvian andes where that’s not an issue.

All of this is backed up by third party testing (allegedly)
