The wooden window frames set into the stone were pretty miserable looking. Not just caked in old dirt, but they were warped from disuse. In fact, Mo would be shocked if the window could even open with the amount of build-up currently caking the frames. The question wasn't whether or not it needed cleaning but in the best way to go about it. Scrub off the dirt and then try polishing? Was there any point in polishing first?

With gusto, Mo shoved up the sleeves to his robes and pointed his wand at one of the slats. "Scourgify." The dirt sort of melted under the strength of the cleaning spell, leaving behind the scuffed wood. Sigh.

He pointed his wand again. "Poliotus." Under the just-cast spell, the wood now appeared brightly polished and clean. He moved on to the next slat, repeating the process. "Scourgify. Poliotus." The frame now clean, the whole window seemed to sparkle under the sun now pouring into the room. That was good work, it was.
