Cleaning up the Red Stuff…

Dear Mr. Filch,

What is the best way to clean up blood?

Sincerely,

Oswin

Dear Oswin,

You could try first engaging the mess with your standard mop and bucket, then attacking it attentively with Mrs. Skower’s All-Purpose Magical Mess Remover. But then again, why spend a bottle of the good stuff when you could just write-up a student and make them do it for their detention?

Sincerely,
Argus Filch
