It is important to get into every cupboard, behind the fridge and washing machine, under the bed and everything else that we neglect during the regular cleaning. When we are up and about in our homes throughout the days and nights, billions of skin cells shed and land on our floors and furniture. In addition to them, our bodies have to encounter a wide variety of microorganisms to deal with. The more they become, the harder it gets for us, and we start suffering from allergies, asthmas, and so on. That is why it is crucial every once in a while to have one-off cleaning.
