My 4 year old granddaughter spent the night last night and smuggled her Dora Chapstick into the guest bed on the brand new cotton sheets. And as you can imagine the top came off and it was all over the sheets. I have washed them twice and the greasy stain has not come out. First time was with Dawn and the second with Oxiclean spray. I did dry them after the dish detergent but hung on a makeshift line the second go round. Any suggestions are welcome.
