What's the gentlest way to remove contacts from your friend list?

I normally use a little carbon tetrachloride or acetone (nail polish remover) and gentle rubbing, though some people swear by duct tape ... lay it down over the contact, wait for a couple of hours to set, and carefully peel it off. Never use a putty knife or spatula... you will shatter the contact and may scratch the underlying substrate.

Eventually someone is going to combine Guinness' foam technology with canned coffee.
