Toothbrush Holder
This benign-seeming bathroom cup is one of the germiest spots in the house: the average holder is crawling with more than 2 million cells of bacteria. Bamboo and wood may look attractive, but they're difficult to clean, so go with a dishwasher-safe material like brushed stainless steel, or plastic, and clean it once or twice a week.
