Mrs Skower’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!" According to Mathilda Grimblehawk, the solution has a rather distinctive strong, acrid smell. Rita Skeeter rested her parchment on this crate when she interviewed Harry Potter inside the broom cupboard just before the start of the Wand Weighing ceremony in 1994.
