Message: I found your website after we already dyed some tshirt. Admittedly we used Rit dye! (shame on us). This was our big Easter family project, is it salvageable? My husband mentioned a concoction using vinegar? Do you have any suggestions?

Don't use vinegar! It won't help. What you should use is Retayne. See:

http://www.pburch.net/dyeing/FAQ/fixrit.shtml

Retayne will work if you followed the boiling-water recipe required for Rit dye. If you used cold water, nothing will work, because Rit is a hot water dye. Either frame the shirts as they are, or wash them out and try again with either good fiber reactive dye, or the right recipe for all-purpose dye.

Good luck.
