A cleaning spell is a generic term for a spell used to make an object cleaner, such as the Scouring Charm or Skurge Scouring Charm. Ronald Weasley did not know many, if any, cleaning spells.[1]

Behind the scenes

Ron Weasley: "Brilliant! Mum would've made us clean those out by hand. We'd've still been scrubbing them at Christmas!"
Hermione Granger: "If you'd just take the time to learn some cleaning spells..."
Ron Weasley: "Who wants to spend their time cleaning things up? This was much more fun!"
Ron Weasley and Hermione Granger argue about the method Ron chose to clean Fred and George's old cauldrons[src]
