Will Rit Black Liquid dye mix with other clothing if I wash it again will it start to leak into other clothing
And if it does leak is there a sure fire way to prevent it from damaging anything?
I would say yes, I dyed a pair of pants dark chocolate brown and even after several washings if I throw anything lighter colored in the wash w/ it, it gets stained…To save on that trouble just wash it with other black things on cold temp.
