How do dragons get clean?

Dragons, as mythical creatures, are often depicted in various ways depending on cultural lore. In many stories, they might clean themselves by bathing in rivers or lakes, using their fire breath to scorch dirt away, or simply by rolling in the earth to shed scales and debris. Some tales suggest they have magical abilities that allow them to maintain their scales without the need for physical cleaning. Ultimately, the method varies based on the specific mythology or fantasy setting.
