I would certainly try this first. But if you do it the other ways like with the Q-tips and you rinse, reverse the quilt so the grease stain rinse away from the rest of the fabric. That way any of the stain will not penetrate through the back. As long as you have not tried to wash the quilt already you should be ok. Hopefully the stain didn't go all the way through the back.

You can purchase this spray at Hancock's Fabrics. I use it often and it works great.
