Cris took an exaggerated bow before straightening up and grinning. "Thank you and you're most welcome. The cleaning spell? Yes I can teach you that but yes they will also teach you that at Hogwarts along with a whole bunch of other interesting spells."

"When learning spells, my Professors always tell us to first learn the incantation, which is actually the words to the spell. You need to say it correctly or the spell might not work the way you want it to. Then once you've mastered that, you learn the spell's wand movement, like this," Cris waved his wand followed by a flick.

"For the spell I just did, the wand movement as you can see is pretty straightforward. I just pointed my wand at the areas I wanted cleaning. Now that's the easy part. The hardest part is getting the spell to work, and it's not just fancy wand waving and saying the incantation. The hardest part involves this," Cris explained as he tapped his forehead with his finger.

"Concentration is what is important. That and your intention," Cris paused when he realized that he was sounding like one of his Professors.

He laughed as he looked at Monty,"I have a feeling that most of what I just told you, just went flying over your head. I know it did when someone first tried teaching me to cast my first spell." he chuckled as he recalled that memory.

"I've always believed that practice is always better than theory. So would you like to try casting that cleaning spell? You will find it very useful in some of your classes especially Potions. Don't worry if it doesn't work out the first few times. With lots of practice, you will eventually master it," Cris smiled encouragingly at Monty.
