Is there an objective metric for measuring cleanliness?

I define the truth to mean that which is in accordance with reality. Reality is the world or the state of things as they actually exist, as opposed to an idealistic or notional idea of them. My judgment about a claim or proposition is that it is true or false. The only other option is ignorance. There is no evidence for "the truth" being in accordance with reality. There is evidence to suggest that "the truth" is merely a human construct that resides only in our imagination.
