How do you remove grass stains from silk?

I got a couple of grass stains on a white, silk dress. I soaked them in soda water - one came off but there's still one grass stain that won't budge.





It's a delicate garment with beads so can't use bleach or any rough methods.

Sponge (the method of using light strokes with a dampened pad working outward from the center of the stain) the area with a dry-cleaning solvent such as Afta Cleaning Fluid. Apply dry spotter to the stain and cover with an absorbent pad dampened with the dry spotter. Let it stand as long as any stain is being removed. Change the pad as it picks up the stain. Keep both the stain and pad moist with dry spotter. Flush (the method of applying stain remover to loosen staining materials and residue from stain removers) with one of the dry-cleaning solvents and allow to dry thoroughly. When working on carpets, be sure to blot up the excess liquid during the procedure and before drying.
