If you're having trouble achieving a fresh, clean smell in your house, rest assured—doing so generally does not require industrial-strength chemicals. Unless you're dealing with a mold infestation, all you need to get the job done is some natural odor eliminators. Go natural! Smell great!
But first you need to identify the source of the stink. Take a step back and look at your cleaning habits: If your bathroom smells musty more often than not, it probably means you're not cleaning enough ... or using the right cleaners.
