Sorry, I know I used both on all the washing I did and thankfully it worked! Otherwise I would have had a ton of unusable yardage.
Retayne FIXES dye to fabric and should be used in cases where you are concerned that a fabric dye may bleed. Use
Retayne as directed, as a pre-wash
or before putting suspect fabrics into a quilt.
Synthrapol is a special detergent that suspends dye particles so that they do not reattach to fabric.Apr 12, 2012
