The phone should be fine. Just submerge it for a few minutes in a container of clean water. Avoid rinsing it under a faucet, because the pressure of the emerging water could exceed what the phone is rated to withstand.
I think Epson salt has magnesium as a component. So over time this probably with begin to effect the various components in your phone.
Washing it off, I agree, I really don't think this would help.
