Salt stained on car carpet

Hey guys,while waiting for my car to get back from the shop, i thought i'd get started in finding the best way to get rid of the dried up salt on my car floor. It's pretty thick, it was left over from our crazy winter that never seemed to go away. I was just wondering if you guys knew the best product or trick to get this out instead of sending it to a detailer and getting it cleaned.



Thanks!
