I ask you, the smartest people I know.

Salt is used to set dye (a mordant) in a fabric, such as when tea dying muslin. Salt is also one of the #1 suggested methods for removing a fresh blood stain from fabric.

This is breaking my brain. Why?

My guess is that dyes are not protein-based. Does that sound right?
