Help with Stain Problem

I love Citiknits clothes which I order on QVC, they are great for packing, you can literally roll them up, put them in the suitcase and they come out perfectly. They also fit well and look pretty good with my figure type. I got a new outfit, top and crop pants to take on our upcoming trip to Hawaii. As is usually the case the label said to wash in cold water, by hand before wearing and lay flat to dry. I did this and laid the pants on top of my dryer. It left a horrible, big stain on the top and front of the dryer! I tried Arm & Hammer Essentials cleaning liquid, Shout and even Clorox bleach and nothing worked to remove the stain. Any ideas, please!

Try one of those Mr Clean magic erasers???? I got some stains out of my sink recently that I thought were permanent!

Perhaps Baking soda would work?
