I just used both green and black ultra - clean markers to mark a quilt for one of my grandsons, and even after pressing some of the marks with a hot iron, they all came out in the wash without a problem.
I had a bad experience with some Chaco markers that didn't wash out and will never use them again, but I love these Crayola markers.
