Removing cooking oil from a polyester Parker

[TellySavalashairbrush]

Managed to get cooking oil on my favourite polyester Parker jacket. Tried using washing up liquid on the stains , but they haven’t come out. Any suggestions greatly appreciated.

Baking soda and white vinegar can be good for getting grease out. Mix it into a paste and let it sit for a bit - it goes all fizzy! Dishwasher tablets also good for breaking down grease although I've never tried this method myself.
