Nope, I haven't tried Dawn yet. I have to run to the store in the morning so I'm going to pick it up. I did, finally get it out of the dark purple which was my main concern but it's not coming out of the tan still. My LQS suggested Oxi-Clean and that took it out of the purple. I just can't figure out why it would come out of the tan scraps and not the tan in the quilt. Both were pre-washed.
