Janice took a bucket and a broom and put it on her side. She then filled the bucket with concentrated cleaner. She held her breath from the start, since the smell of bleach had always succeeded in making her dizzy and hurting her eyes, so she never actually mopped the floor with strong bleach. She took out her wand, said "Aguamenti" and waited until the bucket is half full. "Finite," she said afterwards. She breathed out, and inhaled the once-the-strong-smell-of-bleach. She knitted her eyebrows and practically ran to take a sponge.
