I see you are a drycleaner and therefore the Knowledge on all things clean, please can you help me rescue a silk dress my dp ruined ? He spilled creme de cassis on it, in a big spray up the length of the dress 
I took it to the dry cleaners and they charged me so I think they cleaned it but said that the cassis wouldn't come out as they couldn't apply heat/steam as it was silk.
This happened ages ago a year I think so it has dried in, but nothing else has been done to it, do you think I could try anything to get rid of the stain ?
Please help ! Thank you
