Krytox GPL 205g0
The default linear-switch lube. Krytox GPL 205g0 is the thick grease the keyboard community reaches for on linear switch stems and springs, smoothing travel and deepening sound without making the switch sluggish when applied thin. It's the reference lube that guides and tutorials assume you're using.
View on Amazon Editorial illustration.Lubing linear switches removes scratch and gives that smooth, deep sound and feel, but the keyboard hobby is specific: for linears you want a thicker grease, and the wrong lube makes switches mushy or sluggish. One product comes up more than any other.
The switch itself still sets the baseline feel and sound. Lube can reduce friction and spring noise, but it will not turn a poorly chosen switch into the right one for you. Test a few switches before committing to an entire board, especially if you have never used 205g0.

What should you look for in switch lube?
Match viscosity to the switch and your preferred feel, then use the smallest amount that produces an even film. Make sure the product is intended for the plastics and materials in the switch, and keep lubricant away from electrical contacts unless the instructions explicitly allow it.
- Grease for linears: a thick grease like 205g0 suits linear switches.
- Thin application: too much lube makes switches sluggish.
- Switch parts: lube stems and rails; a light spring lube kills ping.
- A little goes far: one small tub does many switches.

Tribosys 3204
A slightly thinner alternative some prefer on lighter linear springs or on tactiles, for a touch less drag. Comparable results; 205g0 is the more universal pick.
How to avoid over-lubing
Start with a small test batch and compare it with an untouched switch. The coating should be barely visible, with no blobs collecting on the stem or housing. If the switch returns slowly or feels damp and muted, too much was applied. It is easier to add a little than to clean a whole board.
Bottom line: Krytox GPL 205g0 is the go-to linear-switch lube the hobby is built around; Tribosys 3204 is a slightly thinner alternative.
