Cleaning!

A man is just about to get a CD out of a cabinet when the phone in the kitchen rings.

Hello, says the man answering it.

Hi, says a high woman’s voice. This is Tiffany the housekeeper.

Oh, says the man. Hi Tiffany.

Hi, Mr. Birschman. Sorry to call so late. I figured you’d be back later, so I planned to leave a message. You see, I had a problem when I was cleaning the bedroom.

What sort of a problem?

Well, when I was trying to make your bed, your envelope of emergency money, you know, the one you keep under the matress, it fell out.

Well, what’s the problem, Tiffany?

Well, I wasn’t sure just where to put it back, so I just put it under the bottom left corner. Is that okay?

Yes. Thank you for telling me that, Tiffany. I appreciate it.

Oh, also, when I was vacuuming the living room, I found that diamond ring you’ve been missing.

That’s wonderful, Tiffany! By the way, where did you put it?

In the jewelry box on the dresser, of course!

And how did you lock it?

First I turned the key to the right, then I pulled it out and tried the top to make sure it was locked, says the housekeeper, revealing how well she remembered his instructions.

Good! And where did you put the key?

In the top right cabinet in the kitchen, under the good china.

Fantastic! says the man, impressed.

Oh, and I took the courtesy of wrapping the keys to the Porsche in that adorable little box. I know your wife is going to be so surprised.

Stupendous. Thank you so much, Tiffany. You are really a great housekeeper.

Thank you, Mr. Birschman, and have a nice night.

You too, Tiffany. Good night.

The man hangs up the phone, turns to his buddy, and says with a grin, This is going to be the easiest robbery ever!

Cleaning

Cleanliness is the absence of dirt, including dust, stains, bad smells and clutter. Purposes of cleanliness include health, beauty, absence of offensive odor, avoidance of shame, and to avoid the spreading of dirt and contaminants to oneself and others. In the case of glass objects such as windows or windshields, the purpose can also be transparency. Washing is one way of achieving cleanliness, usually with water and often some kind of soap or detergent. In more recent times, since the germ theory of disease, it has also come to mean an absence of germs and other hazardous materials. In industry, certain processes such as those related to integrated circuit manufacturing, require conditions of exceptionally immaculate cleanliness which are achieved by working in cleanrooms.

A recent shift has now taken place to recognise that ‘dirt’ may play a useful role in our immune systems. This shift in thinking can be traced back to 1989, when David Strachan put forth the "hygiene hypothesis" in the British Medicine Journal. Strachan looked at the records of 17,000 British children and found that the greater number of older siblings they had, the less likely they were to come down with hay fever a disease which, despite its name, is far more common in the city than the country. Strachan wondered if the older children were bringing home more viral infections to their younger siblings, priming their immune systems so they could better tolerate pollen. The "hygiene hypothesis" has now been linked with asthma, allergies, intestinal diseases including Crohn's disease, childhood leukaemia and atopic dermatitis and the list is growing. It can apply to humans, animals, clothing, food, eating utensils (plates, pans, cups, etc.), other movable objects, floors, windows, walls, toilets, etc.

Cleanliness is essential to successful electroplating, since molecular layers of oil can prevent adhesion of the coating. This industry has developed many specialized techniques for cleaning, as well as tests for cleanliness. The most commonly used tests rely on the wetting behaviour of a clean hydrophillic metal surface.

Cleanliness is also important to vacuum systems to reduce outgassing.
