The difference between clean and tidy? Looking at the ads popping up - Clorox. LOL I'm going to use the definitions of showers. Specifically two types, although there are many.
1) Clean - the 15 - 30 minute shower where one actually scrubs every inch of skin. You know the ones if you have a chair in the shower you sit down and scrub the underneath of your feet.
2) Tidy - the OH S***, I forgot to set the alarm for work. Lions, tigers, and bears, oh my comes to mind. So, you do the dunk and run. You turn on the shower, not taking time for the right temperature, do the pertinent parts, and get out.
Or another analogy is this is tidy and hub would have been clean :)
