How do you take oil stains out of silk?

http://www.youbeauty.com/life/everything-need-know-getting-oil-stains-silk/

read the above... however depending on what type of oil and what type of silk and how long the stain has been there well it will be a gamble IF you can remove it... BUT the other option of course is go to a professional dry cleaner tell them what the stain is and let them try with most likely a better result

Is that a euphemism?

A good pair of scissors should do the trick

Try putting shampoo on the oil and soaking the item in water. I used to wash my silk blouses in shampoo and rinse them in conditioner.

You can't.
