Dying with ammonia is not nearly as pleasant as dying with vinegar, but cotton and bamboo are not as dye friendly as wool. Spilling a vinegar dye on my arm isn’t such a great concern. It will wash off if I get to it fast enough. It seems the blue ammonia based dye I mixed up to dye a shirt for my husband, simply won’t scrub off, no matter how quick my response is.
Oh and the smell….
