Himalayan Salt NOT Food Grade (Caldy Valley CH3)

Does anyone want a large tub of Himalayan Pink Salt for their bath or to put on their driveway when it snows? I bought a large sack of this years ago but never even considered it might not be food grade so I have been putting it on my food for years with no ill effects thankfully. But I have now realised it wasn’t food grade so think I’d better stop eating it! I am in Huntington by Caldy Valley Road.
