Snape explained, "As you can see, its effects include cleaning all kinds of grime. It even works on dragon blood."
Dumbledore hummed. "When was it completed? With your guidance?"

Snape pressed his lips together and said nothing more. He simply limped away.
"Vizet, take this."
In the corridor, Filius Flitwick pressed something into Vizet's
