This isn't specifically a craft question, but figured you all might have the answer.

My mom has a fountain (the decorative kind) that keeps getting gunked up so that the pump stops working. She cleans it out, but a day later it gunks up again. Does anyone know of a household-type something that might clean it out good? (i think she's tried vinegar, but not sure)

Thanks in advance!
