Dry cleaning help

[Mrsdave76]

Hi guys.
I am hoping to sell a beautiful silk evening gown. The only thing is it has a white wine mark on the front and it's dry clean only. Is there any way I can gently wash this in my washing machine without ruining it?

If you was it and the stain does not come out then you may "set" the stain into the fabric If you dryclean then you have the option of then sponging afterwards as the stain will not have set.
