Just to let you each know I place three each blue and three yellow stripes of chalk on my scrap piece of white material. I tried just plain water on one of each color. I used a very used spin brush to work the water in. The blue came most of the way out. The yellow stayed. Maybe not as wide or quite a yellow however definitely still there.
Then I used a tide to go pen on the second of my stripes. The blue went away. But yellow the same as the water. I tried the spin brush on it too. Still there.
3rd trial. I used Shout stain remover. Same results as the last two tries.
I presently do not have any of the oxi-clean stuff will have get a small sample and try it.
Hope this helps everyone else out there. Don't use your chalk unless you are going to quilt it that day and deal with it is what I learned.
The only other thing I can think of is to give my quilt a gentle but through cleaning as soon as it is finished. Still need to do more quilting through out the quilt. I will post a picture of it when it is completely finished.
