She was clearly an expert at glass cleaning charms and all things glass cleaning and all things glass. Clearly. Alice decided she was going to move on to becoming an expert at all things cleaning, too, and that required more spellwork. Scouring charm next? That was simple, she knew it and could already preform it with ease. It was already hardwired into her brain, so she started on it immediately, moving back over to her desk and pointing her wand at it. "Scourgify."

It seemed to be clean enough, so she stepped back and cast it on the legs of the desk, too. Those were just as dirty as the table, weren't they? "Scourgify." Alice scrubbed off all of those with the spell until they were shining.

Easy peasy.

More fistpumps.
