The best way to deal with crayons is to get advice right from the horse's mouth....Crayola! See their removal tips at their web site.
For another option, here's what another source says: Scrape excess crayon with the dull edge of a butter knife.
Wash in hot, soft water with soap, such as Ivory and 1/2 cup baking soda for 10 minutes.
If the stain remains, work soap paste into the stain. Wash 5 minutes. Rinse.
To remove any remaining color use bleach or color remover as safe for the fabric. Always test for color fastness.
