Your hands can, presumably, never be cleaner than the water with
which you rinse them.

Not really true and no doubt the reason for hand dryers*. Water, even
'clean' cotains and is a good host for many bacteria. The object
therefore of such a dryer is to eliminate the host, the water and, I
suppose, supply sufficient heat to kill any nasties that remain. While
personal I'd rather have (paper) towels any time, logically I think that
if you're a hygiene nut, then a dryer is probably better.

A few options that these surveys never seem to consider is what happens if:

1. You don't wash your hands at all

2. You rinse them without soap

3. You wash (or rinse) them, use neither paper towel nor dryer, and let them
dry naturally

My dictionary (Collins Compact English Dictionary) suggests that "drier" is
the adjective and "dryer" is the noun, although it says that "dryer" can
also be used as an adjective.
