Maybe a good idea to work for a short stint in a commercial kitchen?

Not a snark.. it's quite eye opening to see (and actually use) how much food a piece of commercial kitchen equipment processeses in a day and then how much effort it takes to clean them.

One can also try googling for other more detailed versions showing all the efforts in digging out all the burnt sediments/sludge :)
