Easy enough. Zeke grinned as he remembered doing the exact same spell on Amara before. He took his wand out and aimed it at his desk but then a thought came to mind. Err, those exploding dust in their faces. The Gryffindor hesitated for a moment and watched as the others attempted. Thankfully, no more of that morning dust face wash. Safe.

Again, he pointed his wand at the desk. "Scourgify!" Smuuug faaace. Now his desk was as good as the Professor's. Or not yet. One more. Okay next please. Poli....something...sss.

He stared at the board. Poliotus. Poh-lee-oh-tuss?

Before he continued, he saw the Gryffindor girl give him a thumbs up. Why? He eyed her desk. OHH. She'd done Scourgify. Well done, little girl. Zeke gave her a thumbs up back. That was his apprentice...somehow.

'Back to polishing. Errr, an S shape right? Why an S though? Why not a Z? Z looks better. B'sides Zeke starts with Z.'

For fun, he just traced out a Z in the air with his wand about five times. Just because. Back to work Zeke. Get this over with so you can get your ice cream.

After about a couple of practicing the wand movement along with reciting the incantation in his head, time to get real. YEAH.

"Poliotus!" The Gryffindor traced the S above his desk, and TADA! Good 'ol shiny wood. Good enough to eat ice cream over. I scream for ice cream.

Done. He sat back down in his CLEAN desk, satisfied with the work he's done.
