Need a hand during dinner prep? You're likely using one to open the refrigerator door -- even if you just finished handling raw meat. If left untreated, refrigerator, freezer, and oven handles become a breeding ground for germs and bacteria. Scrub handles down once a week with a mix of 1 part hot water and 1 part vinegar.  

Keep your pearly whites clean and your toothbrush holder cleaner. Throw the dirty bathroom accessory in the dishwasher once a week, or sterilize it by hand with hot water and soap.

Think of all the times you've coughed, sneezed, or blown your nose at your desk. Now think of the last time you cleaned your mouse and keyboard.

Reusable shopping bags are great: They hold a ton and provide an environmentally friendly alternative to plastic. However, the bags can start to smell and become a breeding ground for bacteria and mold if not cleaned regularly. Wash cloth grocery bags in your laundry machine, or invest in plastic bags that can easily be wiped down.

It's easy to just refill ice cube trays without a thought, but trays are susceptible to picking up food remnants or odors inside your freezer. Each time they're empty, give the trays a thorough wash with hot water and dish soap.

Put down the bottle. Before you take another sip, draw a hot, soapy bath for it. Let soak for five to 10 minutes. Use a bottle brush to scrub the interior, and utilize a toothpick to get inside the mouthpiece. Rinse thoroughly. 

Faucets are hands-down the dirtiest thing in your home. Scrub handles daily with hot water and dish soap. For a shiny surface, make a paste with baking soda and vinegar, apply it to the faucet, let sit, then rinse off.
