Exorcism Juice  is a potion that can excise a demon from its human host. It appears to be caustic to objects, such as a spoon.
During an undercover investigation at Lewiston Girls Academy, Ray Stantz used Exorcism to concoct a batch of Exorcism Juice in a janitor's closet. However, he failed to hit Kestrel with it and wasted the juice. Ray and Slimer quickly made a new batch in Ecto-1's mini-laboratory then gathered it in a pump sprayer. They doused Kestrel in it before she could imprison her human targets. Kestrel vacated Egon Spengler's body almost instantly.
