I had some PSU fabric and I had made a doll quilt out of it a while back. It ran and ruiened the quilt, so before I used it this past weekend I washed it according to the directions in Retayne. It seemed to work well on the fabrics, no runs, but the inside of my washer was totally splattered with blue dye and I had to scrub the tub before doing the next load. Have any of you had similar problems with this product?
