Charm to Cure Reluctant Reversers
From UnknowableWiki
The Charm to Cure Reluctant Reversers is a spell probably used on broomsticks, since it is mentioned in page twelve of the Handbook of Do-It-Yourself Broomcare, which came with the Broomstick Servicing Kit that Harry Potter received for his birthday from Hermione Granger. Harry tried to think about it in order to avoid listening to Aunt Marge's complaints about the Potters (PA2).
