Got the proof! WD-40 and/or a combination of 2 cups baking soda with liquid tide and oxiclean gets crayons out of clothing! I ran old rags through the dyer all night long and nothing came off on them so I suspect the crayons are in hiding or the jeans absorbed them all. I think the dryer is fine.
Off to buy more WD-40 and prepare for other chaos today.
Spent the evening working on the clothes and the dryer and catching up with the wife.
