Vinegar and salt (works equally well) operate by denaturing the feather (or hair or skin for that matter) protein (keratin and similar proteins) so that many of the pores close. In effect it locks in dye in the feather.  Henk ==========================Heisenberg was right!======================== | Dr. Henk J.M.
