You could well be right. But perhaps the question you should asking is why should it be necessary to be regularly carrying out (or avoiding) any of those issues on something as low tech as a PB. In comparison I have a breadmaker which is slightly more technically advanced only cost a little more than a PB, and its been used 3-4 times a week for 5 years and all that happens to that is the ingredients go in, we plug it in, press some buttons, and a few hours later we get a loaf. And all we have to do then is to wash out the bread tin. There must be many other similar examples.
Another example would be a pair of shoes. Why should I bother to prep such a low tech item by correctly installing and tying the lases before going out. (I wonder why I regularly fall over in the street?).
Please don't take this personally terrym, I'm just pulling your leg.
