Here is what I found:
The first thing to do is find the culprit and pull it out. Then rewash all the whites using a nonchlorine bleach or a cup of white distilled vinegar in addition to your regular laundry detergent. Do this BEFORE you put the clothes in the dryer.
If you have already dried the clothing or the dye transfer is heavy, you will need to take time to soak the clothing before rewashing. Mix a solution of oxygen-based bleach (Clorox 2, OxiClean or Tide Stain Release) and warm water following the package directions. Submerge the stained items and allow them to soak for 8 hours. Check the clothes and if the dye stains are gone, wash as usual. If they remain, soak for another 8 hours with a fresh solution and then wash.
Use the same oxygen-based bleach soak for colored clothes that have dye transfer from other clothes or within the fabric pattern.
