"Ectoplasm is an unpleasant greenish substance left behind by certain ghostly beings. In some places, it will block doorways and openings. You can cast Skurge to get rid of it."
Filius Flitwick[src]
Ectoplasm is a sticky, viscous green substance left behind by ghosts and other spirits[1] that accumulates over time.[2] It is strong enough to act as a powerful adhesive (making a loud churning sound when doing so),[3][1] but it also harms humans should they come into contact with it, meaning it is also a poisonous substance. This can be a great annoyance, as it is typically found blocking doorways. As a result, wizardkind generally considers ectoplasm to be unwanted filth.

"In my day we had to take shovels to this stuff, you know."
Nearly Headless Nick on cleaning ectoplasm[4]
During the Middle Ages, the typical means to remove ectoplasm was by using shovels.[2] Fortunately, some time after 1492, ectoplasm could be cleaned up by using Mrs Skower's All-Purpose Magical Mess Remover, or for the more magically inclined, the Skurge Charm.[3]
