One of the kids left a blue crayon in his pants pocket. The crayon must have come out of the pocket in the dryer (after the clothes already went through the washing machine), and it colored the inside of the dryer while the clothes were going around and around while drying. Many of the clothes are marked with blue crayon plus the inside of the drum where the clothes go, is marked with dried blue crayon all over. We have tried various cleaners and have had no luck getting the crayon markings out. Is there a special cleaner or special method to getting out these marks?
