Hairspray!! (yes, a good musical too) It worked - on all the marks, even the darkest. Didn't even blot (MFord, I didn't see your note until just now) I simply sprayed it on, waited about 2 minutes, then rinsed. It definitely took the lightest of the marks out, even before rinsing I could not see them any longer. There were a few that I didn't think were going to come out because I could still see them after the 2 minutes, but when I rinsed the fabric they disappeared completely. I am so happy!
