Lubing

Lubing is the process of applying a thin, controlled layer of lubricant, usually a thick grease or thinner oil depending on the part, to the moving contact points inside a switch or stabilizer. The goal is to reduce friction between plastic parts so keystrokes feel smoother and sound less scratchy or hollow.

Switches are typically lubed on the stem legs, the inside of the housing, and sometimes the spring, using a small brush to apply grease thinly and evenly. Stabilizers are lubed on the wire and the housing it slides through, which is often the fastest way to remove the rattle that comes standard on most keyboards.

Over-lubing is a common mistake, since too much lubricant can dampen a switch's feel entirely, slow down spring return, or attract dust over time. Buying pre-lubed switches or a switch lube station simplifies the process for beginners who do not want to disassemble and lube dozens of switches by hand.
