I Hand-Lubed 70 Mechanical Switches: The Real Ergonomic Difference

If you browse custom keyboard forums, enthusiasts talk about lubricating switches with Krytox grease as if it were a religious ceremony. They promise that factory switches are scratchy, dry, and unlistenable until you spend hours opening every tiny plastic housing with a switch opener.

I opened up 70 Gateron Milky Yellow switches, brushed a micro-thin layer of Krytox 205g0 across the slider rails, coated the springs in GPL 105 oil, and assembled the board.

The Physical Reality:

• Scratchiness: In stock form, linear switches have a subtle microscopic friction noise as the POM stem slides against the nylon housing. Lubing eliminates that friction entirely: the key feels like an ice cube gliding across glass.
• Acoustics: High-pitched spring ping is eliminated, lowering the sound pitch to a satisfying muted click.

Was it worth three hours of tedious tweezers work? For a primary daily keyboard you use for 40 hours a week, yes. But for secondary boards, buying pre-lubed switches from the factory gives you 90% of the benefit with zero manual labor.
