Commit to some ground rules to keep unwanted odors from forming in the first place. Never store food in open containers or paper takeout containers, as smells can seep out into the fridge. Instead, use glass or plastic containers with tight-fitting lids. Label and date leftovers so they don't hang around too long. Keep highly perishable items on the top shelf, where you'll see them and remember to use them before they go bad. Wipe down messy jam jars, ketchup containers and drippy syrup bottles before you put them back. Place plastic lids under bottles and containers that are prone to leaking. A little extra effort now can prevent a smelly problem later.
