I'm all for environmental awareness - but it's a bit like the people saying, oh, why do you not use re-usable containers for everything, or do you really need to dishwash everything?
Things like food safety, and not making your customers sick are enshrined in law - and that's a good thing.
Even at my work, they aren't allowed to re-serve/re-heat things that have been served once, due to cross-contamination.
You don't! Unless you have flies and cockroaches infested kitchen, some stray bacteria left after just water-washing will be much less harmful than eating the stuck-on-surface dishsoap (which does not rinse off completely, since it's hydrophobic). I have an even worse opinion of people constantly bleaching their countertops. shudder
As an anecdote, I once had a misfortune of living with a guy who would never rinse off the dishsoap from the dishes at all, just leave them out to dry still covered in suds!
Soaps and detergents are not hydrophobic. They are part hydrophilic and part lipophilic which is how they pull lipids into the water when you wash something.
The masks are there to survive sudden cabin decompression at high altitudes where the atmosphere is too thin to breath. There is only enough oxygen to last a few minutes.
