Hi!
You remove dried in poos by placing your piggy in a bowl with no more than 1 inch of warm water to soak the poos. Gently work off as much as you can and repeat the process as many times as needed; caked poo can be rather tricky to remove, especially when caked against bare skin. Dry off your piggy and keep indoors, warm (but not hot) and out of any drafts until they are fully dry.
