This kid got butter on her coat from the popcorn it won’t come off her coat and her moms mad how do I fix it? (Nice and serious answers only?
Try taking it to a dry cleaner
dry clean it if it's wool. If it's washable, try good quality dish detergent (the one that gets grease out of your way.)
As others have stated, a dry cleaners can remove it. Just be sure to tell them it's a grease stain. They have special soaps & solvents to remove certain stains.
try washing it off with a cloth or put it in the washing machine then apologise to the mum.
Depends on what the coat is made of. If the coat isn’t washable, have it dry cleaned.
