IIRC they could be cleaned by immersing them in water.
Good used Model M clicky keyboards still sell for high prices.

Yes they can be immersed. Back in the 80's I was the 1st line of defense for PC repairs, and often the last line. I had a co-worker dump almost an entire cup of coffee into his IBM keyboard - worse he heavily polluted his coffee with sugar and creamer (I drink mine black if you can't guess). Fortunately I was nearby and popped that keyboard off the PC before anything could short. All staff had been previously warned that drinks should not be placed adjacent to or in this case, above office equipment.
Ran over to a local electronics supply store and purchase a container of liquid (not spray) electronics part cleaner. Using the office janitor's closet with its utility sink, I thoroughly washed the keyboard with water and a small amount of dish detergent. flushed it well and let it drain as well as possible, but not dry. I then liberally doused the keyboard with the the cleaner (which is plastic safe by the way) to flush all the usual electrolytic contaminants found in tap water off the circuits.
Luckily it was a Friday and the office was not open on weekends. The keyboard was pretty potent and needed to air. My co-worker complained his keyboard still had a chemical odor for the following week, but nobody gave him any sympathy. So far as I know that keyboard was still in use when I left that job a couple years later - but that co-worker swapped it out at first chance when another co-worker left employment!

IMO, yes and no. The keyboard was meant to emulate the feel of the IBM Selectric typewriter, which was fairly pervasive in many corporate offices. But the bigger reason is many corporate offices had IBM service contracts and overall IBM service was reasonably quick and reliable. Management thought the same would be true for PCs. Turns out that while also electronic, typewriter repair staff weren't all that sharp at PC repairs. I knew as much or more than the IBM people, which at the time wasn't saying a lot. But as they say, the die was cast and IBM branded PCs found their way into a lot more offices. It just so happened that Microsoft was along for the ride.
