Okay, i have a pair of shorts that got some ink rubbed off on it somehow from a plastic bag…its just surface and isnt like a soaked in stain but i rain it in the wash and it didnt come off

How do i remove the ink stain?

Next, i was eating a chocolate icecream drumstick, and a piece of chocolate fell and melted on my shirt and it left a chocolate stain aswell as a oily type stain

How do i remove the chocolate/oily stain?
