What Lurks Under Your Refrigerator?

We bought a clever little tool at Home Depot yesterday to deal with the dust and whatnot under the refrigerator.  What disgusting results! Also good for your dryer's lint vent. It's called a Dryer Vent Brush.  This is one of those things that are recommended at least once a year to prolong the life of your refrigerator.  It takes no time at all and the tool is less than $10.
