Germaphobic? You may be living with more hidden grime than you think. We asked Nesties: What are your most commonly overlooked and frustrating dirt zones? Here’s what they told us -- plus, some tips on how to effectively sanitize each spot.

Underneath and behind appliances

Even if you routinely scrub the inside of your fridge and oven, it’s still not enough. Pull your freestanding appliances away from the wall and you may be in for an unpleasant surprise. With refrigerators especially, you can expect to see dust from the fridge’s coils (remember to clean those too, with your vacuum’s crevice attachment), plus errant spills and leaks. Mop up the area as you would normally and make sure to let it dry completely before replacing the appliances.
