D.K.
I had the same problem but it wasn't my kids that left the crayon it was me. I worked at a waitress and at the end of the night I cleaned up and had a habit of putting all the crayon I found in my pockets and forgetting and washing and drying them OH what a mess I messed up my husband Football Jersey and he was mad!!!! I tried everything and nothing really worked I had to replace the jersey and everything esle that was in that load. Please let me know if you come up with anything
