Because of the fact that we spend about 1/3 of our lives in bed, keeping the sheets and blankets clean on a regular basis is often a necessary chore, but what about taking care of our mattresses? Chances are, you may rotate your mattress a few times per year, which should extend the shelf-life of your bed, but how often do you actually clean your mattress? The average person will do this maybe once or twice a year (or not at all), and you may be shocked to find out how much filth you’re accumulating on an annual basis, and remember, this is where you sleep!
