Scrubbing in Maine

From the text:

I was taught to clean by my mother, a compulsive housekeeper who employed water so hot you needed rubber gloves to get into it and in such Niagara- like quantities that most microbes were probably crushed by the force of it before the soap suds had a chance to rupture their cell walls. But germs are never mentioned in the videos provided by The Maids. Our antagonists exist entirely in the visible world — soap scum, dust, counter crud, dog hair, stains, and smears — and are to be attacked by damp rag or, in hardcore cases, by Dobie (the brand of plastic scouring pad we use). We scrub only to remove impurities that might be detectable to a customer by hand or by eye; otherwise our only job is to wipe. Nothing is said about the possibility of transporting bacteria, by rag or by hand, from bathroom to kitchen or even from one house to the next.
