I've posted this in chat as well as here to get more advice.
Just washed a dry clean only dress as it had a unknown stain on. The wash was a low temp delicate wash but hasn't touched the stain.
The dress is drying on the line at the min but not sure what I can try next. Is it too late to try something like vanish, am I wasting my money?
The material of the skirt which has the stain on is 97% nylon and 3% elastane.
