When you spend hours using Q-Tips™ to dig...
The operative word was "hours" but maybe you were speaking figuratively.
Yes, I was being a bit dramatic. That can happen when you have a great keyboard; it's always tempting to type more than necessary.
Not my idea of "fun" but with everything broken down to parts, you can get every single component spotlessly clean throughout... I look at that as simply a reassurance for something that I bought from a [stranger] on ebay.
But let's face it, dude: If you're going to catch ebola, flesh-eating disease, bubonic plague, etc. from a KB, you're probably dead the moment you open the box.
Speaking for myself, I'm happy if the keycaps, shell and barrel plate are clean. As long as everything works, the state of the inner assembly never crosses my mind, any more than how clean the bottom of my car is. Life's too short. (Well, my life, anyway... If there are Keyboard Immortals among us, you'd certainly be one of 'em.)
