It's funny because people use Krytox for lube, which EliteKeyboards specifically recommends against:
"These lubes are intended for closed systems or for applications where oil is periodically reapplied to the initially applied lubricant, because the Krytox oil in the lubricant separates from the PTFE solids if the system isn't sealed or doesn't constantly mix the lubricant (which reflows the solids). Sure, it's great lube for high speed bearings and extreme temperature environments, but keyswitches are open systems at room temperature and the oil will soon separate and pool or drip out the bottom of the switch leaving you with gummier solids that no longer flow and just attract dust. We did tests a couple years ago with Krytox out of curiosity, and after the oil separates off a few days or a week later, the difference from an un-lubed switch is mostly negligible."
All that time, and basically a few weeks later, no difference in feeling. If you're going to lube, at least use a different type. Despite the premium placed on automotive lube, there's no difference at all w/ unlubed.
Just as medicine has placebos, I'm convinced that the keyboard community has more placebos than any other hobby I dabble in (bolt-action rifles, billiards, and hydroponics). People do something, and utterly convince themselves it *must* make a difference in feeling, when the science says otherwise.
