How do you remove adhesive from silk?

I used that adhesive for clothing to keep a silk sash in place.
Now I’ve removed the tape, but can’t seem to remove the damn adhesive.

I’ve tried googling this.
A lot of generic suggestions, but I think most of them would damage silk.

So far I’ve tried:
01 Duct tape.
Only seems to work for the big gunky stuff.
The adhesive seems to have worked itself into the fabric itself.

02 Ironing over with paper towel.
Was supposed to transfer onto the paper towel.
Except, in my case, it seems to prefer the silk over paper.

I’m about to try:
03 Freezing and rubbing.
I threw it into the freezer.
Willing to give it a shot, but am kind of dubious.

After that, I’m going to try:
04 Vinegar.
Seems less harsh than other chemicals.
Will it discolour the silk though?

05 Whatever you folks can suggest.

PS Just to complicate things, there’s also very delicate lace involved.
