Shower curtain
While it’s more obvious when glass shower doors are grimy, shower curtains can look deceptively clean. Although they’re constantly exposed to soap and warm water, that doesn’t mean they’re clean.
In fact, they’re a breeding ground for all sorts of mold and mildew if not cleaned regularly (ideally at least once a month). You can run plastic shower curtains through the washing machine on the rinse cycle with a little white vinegar or run it through the wash cycle with detergent.
