You empty the trash in your dorm bathroom before it overflows. Most of the time, at least. But there's one final step before it's really clean. The trash can needs to be cleaned, too.
After you've removed the garbage, place the receptacle in the shower and rinse it inside and out (scrub the bathtub well afterwards). Then, using a mixture of two tablespoons white vinegar to one quart hot water -- or an over-the-counter disinfectant cleaning spray -- spray its surface. If you use the trash bin as a catchall (takeout boxes, yogurt containers), opt for a cleaner meant for pet messes. It will contain enzymes that break down organic molecules, kill bacteria and freshen odors. Scrub the trash can with a brush, rinse it and allow it to air-dry. Then, before you put a trash liner into the clean trash can, place a couple of fabric softener sheets (the kind that are ultra-scented) to help eliminate odors [sources: Apartment Therapy, Real Simple].
