Need help with mystery stain
Hi all, I’m visiting family and my adult nephew’s concert t-shirt has a yellow stain along it the hem that he can’t get out. He said it’s not sunscreen, but he’s not sure what it’s from. Any suggestions?
What he’s already done that hasn’t worked:
-put it through the normal washing machine and dryer
-spot treated with liquid detergent and soaked it in water overnight (I think he uses Arm and Hammer)
My available materials here on vacation: Puracy enzyme stain spray, Tide liquid detergent, Febu, and dish soap. If need be, I can go to the store to buy other things.
Since I don’t know what kind of stain it is, not sure if I should focus on enzymes or surfactants. Should I do a Febu soak just for that area (since there are graphics on the front of the shirt)?
Open to recommendations!
