Scrubbing glass wasn't even that hard, even standing on a chair and working high up. West figured it'd be smart to finish scrubbing the panes he was working on, and then do the glass-polishing on all of them. "Scourgify!" He continued on until he got to a crack in one of the bits of glass.

Well he could deal with that. "Reparo!" Thanks to Dylan, he knew that one. West watched as the crack mended itself so that the pane of glass was good as new. And that was how it was done.

A little more scrubbing and then West leaned back a bit to survey his work. Looked good to him. Time to polish?

So it was... Vitrumonia. He repeated the incantation a few times and the wand movement and then focused on the glass.

"Vitrumonia!" Wand wave. No... nothing. What had he done wrong? West frowned and tried again, being a little more line-y with his wand wave this time. "Vitrumonia!" Wand wave. And slowly... the glass began to shine, looking cleaner than ever without the dull edge it had had even a moment ago. Pleased with his success, West went on to the next pane and polished that one up too.

... what was Mo doing? West side-eyed his former best friend and then decided he was alright. Right. Back to polishing then.
