The Nuisance: The mysterious gunk that congregates around the hinges of a toilet seat. “People replace their seats, on average, every seven years. Just imagine the grime you’d find after that long,” says Melissa Glancey of toilet seat company Bemis.

The Remedy: Bemis’s Easy-Clean Seat, a detachable lid and seat set that twists off easily for convenient de-germing. Available in plastic or wood, in white or beige, the assembly snaps firmly onto preexisting seat hinges. It’s sanitation made simple. $15–$30, Lowe’s, 306 Providence Hwy., Dedham, 781-355-3780, lowes.com.
