In a time where people have become more aware of invisible threats that don't discriminate and don't give warning. A safe and clean environment has now become an expectation to adhere to, from the surgical rooms to the stair handlebars that we use on day to day life, we have made it a conscious effort to adhere to constant cleanliness all around us. 

Walking into a medical office or dental office there is always a distinct smell and feeling that you get seeing shining counters and a fresh, yet chemical smell. A constant effort is made to maintain those environments clean and to remove the risks to individuals that go to those places to ensure their health is at their best. It is there where individuals with that knowledge of the unseen come into play, to be able to maintain that feeling and that sense of cleanliness.

Its the job of those individuals to keep cleanliness up, to maintain that feeling that we know as clean, and to ensure that which we do not see does not harm us in ways that can be prevented.
