vinegar only sets acid dyes. acid dyes are used more often to dye wools and other textiles, the dyes used in other dyeing are not acid dyes and vinegar is not used, it really has nothing to do with setting the color, it has to do with changing the ph value of the fabric so the dye can adhere.
vinegar is used to clean lots and lots of stuff (like your coffee pot)
as for the singe...it really depends on how bad the singe is whether it will (fade) come out. i have tried to save a couple singed things before, without much luck...but that peroxide thing may be the ticket
good luck
