I think salt is something that can stop colour coming out of fibres,
since most dyes, (including stains, of course), are only sparingly
soluble in a salt solution.
Royal Navy sailors used to wash their blue and white collars in
sea-water rather than fresh water so that the colour would not run.

page 98.)

so much snow, and happily researching pigments).
