I had the same problem with a quilt just recently done. When I washed my white became pink. 1/2 cup of bleach in the washer let aggitate for a minute, added quilt and pinks all gone, and the red and blue stayed sharp! I tried so many other products, the color catchers didnt work, synthropol didnt work, so what the heck I thought, whats the worse thing that could happen. Turned out great!
Wishing now I hadnt spent the money on all the other expensive products that didnt come through.
