====== Grand Vessel Wash ======

Once an event, before everything start, this is mandatory.
... It's a task for several people. 

It may be optimized (feel free to adapt), but what worked so far was the following:

==== in order to wash throroughly all the vessels: boilers, jerrican/jugs, thermo bottles, teapots themselves ====

- first a generous "pschitpschit" of vinegar inside. maybe pouring vinegar inside for the large containers. letting it sit a bit and/or swirl... making sure it goes through the mechanical parts (thermo, cannister with a spiggot, boilets).

- then adding 90-100° water... swirling...

-> discarding in the liquid trash

- filling once with 90-100° water and discard.
