There are special pcb cleaners though. Some can even be used when a system is up and running. Stuff can be used for servers for example.
Don't want this to make a multi-page discussion so lets just say we are both right.
But you are right on the drying part. Seen my fair share of people just taking the excess moisture of and booting. The key is in the nooks and crannies.
Tap water does indeed have 'stuff' in it....and once dry will not affect the PCB,I have an SR2 here that has been washed a few times now with no problems
The fact is,washing a board does not harm to longevity if its dried correctly. There is nothing on the PCB that is damaged by water unless its live,this is fact...not opinion.
PCB cleaners are used for the fast flash off capability,enabling faster return to service.
The stuff in tap water enables it to conduct current,the 'stuff' by itself will not,it requires the water suspension.
As for ln2 clockers running equipment for less time...this is true...however,they run it far beyond spec that any faults are shown up quickly.
