I have a silky (but not actual silk, just polyester) shirt that I have managed to get dd's emollient on - it's hydromol so along the lines of Vaseline.
It was washed normally but the grease marks were still there, so I rubbed the marks with neat washing up liquid then soaked in warm water before rinsing and spinning in the machine.
Grease mark looks like it's gone from one place but not others.
Is it ruined or are there other tricks I can try?
