Never deal with a disgusting, moldy shower curtain again. When buying a new shower curtain, wash it before use with a 1/2 cup of salt and hot water. It will never, ever mold! -- Putting this to the test currently! Just soaked the new shower curtain liner in a salt and hot water bath for 30 minutes prior to replacing the old, moldy, disgusting one. Really really really hoping this trick really works! Hate moldy shower curtains! Eew!
