Sure, you know to clean your clothes often and your bathroom, and your dishes. But what about those items we often overlook - those oddball things that could use some regular disinfecting? Here's when to clean what, courtesy of Cooking Light magazine.* Your gym bag. Disinfect it monthly - or more often if your leave it in your hot car after morning workouts. That's the scoop from Tara Oronson, author of the book Simplify Your Household. She says you can toss cloth bags in with your other laundry. For nylon bags, swipe them with a sponge soaked in warm water, with a drop of dishwashing liquid. Then rinse it with another damp sponge and lay it open to dry.* Headphones. Swab them once every two weeks with an anti-bacterial wipe. This should keep your headphone and your ear buds clear of bacteria. Rinse the removable foam covers in hot water and dishwashing liquid, and let them dry completely.* The coffeemaker. To remove mineral buildup and prolong the life of your appliance, do this: Pour three cups of white vinegar and three cups of water into your coffeemaker's tank, and brew the liquid as if it were coffee. But turn off the machine halfway through the cycle and let it sit for half an hour. Then switch it back on and finish the cycle. Once the vinegar mix is done, run two full tanks of clean water through the coffeemaker to clean out the remaining vinegar.
