Hi, Ted, That's one of the reasons today why I keep D5 (Decamethylcyclopentasiloxane, CAS Number 541-02-6) on hand. It ultimately evaporates and it solves problems quickly, when needed. It is safe in that it is used to provide the slipperiness to personal care products and is also used in dry cleaning.
