To lube mechanical keyboard switches, remove the switches from a hot-swap board, open each housing, apply a very thin layer of plastic-safe switch lubricant to the stem rails and sides with a small brush, then reassemble. Use a thin lubricant for linear switches, a lighter touch on tactile stems, and never get any on the metal contacts. The job takes patience, not skill, and the payoff is smoother travel and less scratchy sound.
This guide covers the tools, the exact steps, and the errors that ruin a set of switches. It also explains whether lubing is worth your time, because a full board can take an evening or longer. Product details vary by switch model, so check the lubricant maker’s guidance and the switch maker’s notes for any special warnings.
Is Lubing Switches Worth It?
Lubing reduces friction between the stem and housing, which can make keypresses feel smoother and sound less rough. It does not make a keyboard faster or add any competitive advantage. Think of it as a feel and sound upgrade.
Who benefits most
Typists and players who notice scratchiness, spring ping, or stem wobble tend to notice the change. Linear switches often show the biggest difference because there is no tactile bump to mask friction.
When to skip it
If you like your current keys, if your board is soldered rather than hot-swap, or if you do not enjoy fiddly work, skip it. Desoldering 80 or more switches adds cost, risk, and time. Buying switches that are already factory lubed is simpler for many people.
How long it really takes
Plan on a few minutes per switch at first, with speed improving once you find a rhythm. A full-size board with around 100 switches can easily fill an evening, and a first attempt tends to run longer. Splitting the job across two sessions avoids hand fatigue, which is the main reason housings get cracked and springs get lost.
Tools and Materials You Need
Gather everything before you open a single switch. Stopping halfway to find a tool leads to mistakes.
- Switch puller or key puller: removes keycaps and hot-swap switches without bending pins.
- Switch opener: matched to your switch type, since a wrong fit can crack the housing. Tweezers or a small screwdriver can work for some designs, with more risk.
- Small precision brush: a size 0 or 00 detail brush is a common choice, with soft bristles that hold a tiny amount.
- Switch lubricant: a plastic-safe product made for switches. Linear switches often use a thin oil or light grease, while tactile switches often use a thicker grease on limited areas. Read the product page to match the lube to the switch type.
- Tweezers: for handling springs and small parts.
- Switch holder or shallow tray: keeps pieces sorted and stable.
- Paper towels and a clean work surface: lube spreads easily.
Optional extras include spring lubricant and a bag for coating springs, along with a small brush kept just for stabilizers.
Spec Guide: Matching Lube to Switch Type
| Switch type | Typical lube choice | Where to apply |
|---|---|---|
| Linear | Thin oil or light grease | Stem rails, stem sides, light layer on housing sliders |
| Tactile | Lighter grease or oil | Stem sides and rails only; avoid the bump area |
| Clicky | Usually skipped | Lube can dampen the click mechanism |
| Stabilizers | Dielectric grease or thick grease | Wire ends, housing bearing points |
Exact viscosity names vary between brands, and guidance changes as new products appear. Follow the lube maker’s switch type guidance first.
Step-by-Step Lubing Process
Step 1: Prepare the board
- Unplug the keyboard and remove all keycaps with the puller.
- Photograph the layout so you can restore it.
- If the board is hot-swap, pull the switches straight out. Keep them in order if you want to track which are done.
Step 2: Open the switch
- Place a switch in the opener or holder with the stem facing up.
- Squeeze or pry gently until the top housing releases.
- Lift out the stem and spring, and set them aside on the tray.
Step 3: Apply lube
- Dip the brush lightly and wipe off excess on a paper towel. The brush should look barely wet.
- Coat the stem sides and rails in a thin, even film.
- For linears, add a very thin layer to the housing slider walls if the lube maker advises it.
- Keep lube off the metal leaf and contact area at the bottom.
Step 4: Reassemble and verify
- Drop the spring in, seat the stem, and snap the top housing closed.
- Press the stem a few times to feel the travel and listen for scratch.
- Reinsert it into the board, aligning pins to avoid bending.
Stabilizers and Springs: The Extras That Change the Sound
If your goal is a cleaner sound, switches are only part of the story. Rattly stabilizers on the spacebar, Enter, and Shift keys are often the loudest culprits, and they take far less time to fix than a full switch job.
Stabilizer care
Remove the stabilizer inserts, apply a thicker grease or dielectric grease to the wire ends and the bearing points in the housing, and work the wire back and forth until it moves freely. Keep the grease off the outside of the housing, because it attracts dust. Many builders also add a small piece of foam or tape under the stabilizer to quiet bottom-out noise, though results depend on the board.
Spring lubrication
Springs can ping when they flex against the stem. A light coat of spring lube, applied in a sealed bag by shaking the springs with a small amount of oil, reduces that sound. Too much makes keys sluggish, so use a minimal amount and let any excess drain on a towel.
Optional switch films
Thin films placed between the top housing and bottom housing can reduce stem wobble in some switch designs. They are an extra step with small effects. Try them on a few switches first, and check that the housing still closes without gaps.
Troubleshooting After Lubing
If something feels wrong when you finish, check the common causes before you reopen every switch.
- Keys feel mushy or slow: too much lube. Reopen the affected switches and wipe the stem back to a thin layer.
- A key does not register: the switch may be seated with a bent pin. Pull it, straighten the pin with tweezers, and reinsert it carefully.
- Stem feels gritty: dust or fibers got onto the stem. Clean the parts with a dry brush and reapply a thinner coat.
- Inconsistent feel across the board: amounts differed between switches. It helps to lube in small batches and compare them in order.
- Housing does not close: a spring or stem is out of position. Reopen it and reseat the parts.
Safety and Care Notes
- Work over a tray so dropped springs do not vanish.
- Avoid petroleum products and household oils, which can damage plastics. Use products made for keyboards.
- Wash your hands after handling lubricants, and keep them away from children and pets.
- Do not lube the PCB sockets or contact points.
- Take breaks. Hand fatigue leads to cracked housings.
Before You Start Checklist
- Confirm the keyboard is hot-swap, or that you are comfortable desoldering.
- Buy one or two spare switches in case a housing cracks.
- Identify your switch type and match the lube.
- Set aside two to four hours for a standard board.
- Try a handful of switches first and decide before doing the rest.
Common Mistakes
- Using too much lube, which makes keys feel slow, mushy, or sticky.
- Applying lube to the metal contacts or tactile bump area and ruining the feedback.
- Using the wrong product, such as general-purpose spray lubricants that can harm plastic.
- Forcing a mismatched opener and cracking housings.
- Lubing only some switches, leaving uneven feel across the board.

Frequently Asked Questions
How much lube should I use per switch?
Much less than you think. A faint shine on the stem rails is enough, and if you can see a bead of liquid or grease, wipe it off with the brush and a towel.
Do I need to lube the springs?
Not required. Spring lube can reduce ping and rattle, but it may also slightly soften the return action. Try it on a few switches before committing to a full set.
Can I lube without opening the switch?
Some people add lube through the stem opening, but coverage is uneven and it is easy to over apply. Opening the housing gives a controlled result.
Will lubing void my warranty?
It might. Opening switches or disassembling a board can affect warranty terms with some makers, so read the warranty before you start and consider practicing on a spare set. Opening a few cheap spare switches first also teaches you how much force the housing clips need, which is the most common source of damage for beginners.
