Too much dust under or behind a refrigerator is a bigger problem than you might think. When your refrigerator coils (typically located on the bottom or at the back of the fridge) are covered in dust, the appliance has to work harder to keep things cold or frozen. A vacuum is an easy way to clean away dust, but typically the extension hose on a vacuum isn’t long enough or narrow enough at the opening to fit in the tight space below the fridge. One great workaround is to take a cardboard paper-towel tube and secure it to the vacuum hose with a rubber band, then flatten the tube a little so it fits into the cramped space.
