Mrs Skower's All-Purpose Magical Mess Remover

Mrs. Scower’s All-Purpose Magical Mess Remover is a magical cleaning solution. An advertisement for it at the Quidditch World Cup in 1994 featured the slogan "No Pain, No Stain!"

Argus Filch tried unsuccessfully to remove the words which Ginny Weasley painted on wall of the second-floor corridor at Hogwarts with Mrs. Scower’s All-Purpose Magical Mess Remover. As a Squib, Filch may have relied on the product quite heavily, particularly since a whole crate of it was kept stored in the school's broom closet. Rita Skeeter rested her parchment on this crate when she interviewed Harry Potter in the broom closet 1994.
