How to Clean a Mechanical Keyboard
A properly maintained mechanical keyboard lasts 10+ years. A neglected one develops sticky keys, scratchy switches, and pet hair in places you'd rather not think about. Here's the full cleaning routine.
What you'll need
- Keycap puller (usually included with mechanical keyboards, $2-5 if not)
- Switch puller (for hot-swap boards only, $3-8)
- Compressed air ($8-15, lasts years)
- Soft brush (paint brush, makeup brush, or electronics cleaning brush)
- Microfiber cloth (lint-free)
- Mild soap (dish soap works) or isopropyl alcohol (90%+)
- Bowl of warm water (for keycaps only)
- Small Phillips screwdriver (for disassembly if needed)
- USB cable / port access for testing keys after cleaning

The 5-minute weekly routine
Do this every week to prevent buildup:
- Unplug the keyboard (or turn off if wireless)
- Turn it upside down over a trash can and shake gently — large debris falls out
- Use compressed air between every key, holding the can upright (tilted cans spit liquid)
- Wipe down the keycaps with a slightly damp microfiber cloth
- Done
This takes 5 minutes and prevents 90% of deeper cleaning needs.
The 30-minute monthly deep clean
- Remove all keycaps using the keycap puller. Pull straight up — don't twist or angle.
- Soak keycaps in warm soapy water for 15-20 minutes. Agitate gently.
- Rinse thoroughly with clean water. Any soap residue will feel sticky when dry.
- Air dry completely on a towel. Minimum 2 hours, ideally overnight.
- With caps removed, blow out the keyboard with compressed air. Hold at 45° angle to avoid blowing debris deeper into switches.
- Use the brush to dislodge anything stuck in the gaps.
- Wipe the exposed plate with a slightly damp cloth.
- Test the keyboard with our Keyboard Tester to verify all keys still register.
- Replace keycaps once fully dry.
Cleaning switches (hot-swap boards only)
If you have a hot-swap board and a switch feels scratchy or inconsistent:
- Remove the switch with a switch puller. Pull straight up, gently rocking if stuck.
- Inspect for debris, bent pins, or damage.
- For light cleaning: blow compressed air into the housing.
- For deep cleaning: carefully disassemble the switch (top housing → spring → stem → bottom housing) and clean each part with 99% isopropyl alcohol. Let dry fully (10+ minutes) before reassembling.
- Reinstall the switch. Pins go into the PCB holes — match the orientation markings.
- Test the key with our Keyboard Tester before continuing to the next switch.
If a switch is mechanically damaged, just replace it — new switches are $0.30-0.80 each.
What NOT to do
- Don't spray cleaner directly on the keyboard — liquid can get inside switches and short the PCB
- Don't use bleach or harsh chemicals — destroys keycap legends and plastic
- Don't put keycaps in the dishwasher — heat warps them
- Don't pull keycaps at angles — breaks the stem
- Don't try to fix sticky switches with WD-40 — attracts dust, makes it worse
- Don't soak mechanical keycaps in hot water — warps ABS plastic. Use warm (not hot) water.
Cleaning by switch type
ABS keycaps (most stock caps): develop shiny spots over time. Soap and water work; legends may fade with aggressive scrubbing.
PBT keycaps (most aftermarket): more durable, legends don't fade, can take stronger cleaning.
Pudding keycaps (transparent sides): clean similarly to opaque. Avoid alcohol on the legends.
How often should you clean?
- Weekly quick clean: 5 minutes, prevents buildup
- Monthly deep clean: 30 minutes, removes grime and debris
- Quarterly full maintenance: switch inspection, lubrication if needed, full keycap wash
- After spills: immediately — power off, disconnect, blot with microfiber, let dry 48 hours before testing
Cleaning wireless keyboards
Same process, but extra caution:
- Power off completely (don't just disconnect)
- Protect the charging port — don't get liquid near it
- Don't submerge the keyboard even briefly
- Some sealed boards (like the Logitech MX Mechanical) have IPX ratings — check yours before cleaning
Final tips
Mechanical keyboards are built to be cleaned and maintained. A well-cared-for keyboard from 2016 still types better than most new ones. Set a calendar reminder for monthly deep cleans and your keyboard will outlive your next three computers.
Before cleaning, run our Keyboard Tester and screenshot which keys feel "off" — this gives you a baseline to verify your cleaning fixed any issues.
While you have the board open, it is worth checking your switches are behaving. Our online keyboard tester detects stuck and ghosting keys. For upgrade recommendations, see best mechanical keyboard 2026.

Frequently asked questions
How often should I clean my mechanical keyboard?
A quick clean every month or two and a full deep clean every six months is a good rhythm. The most common cause of a keyboard feeling bad is not dirt but dried-out lubricant and dust in the switch stems, which builds up over a year or two. If keys feel scratchy or sticky, a deep clean is overdue regardless of the schedule.
Can I remove keycaps without a keycap puller?
Yes, for most standard Cherry-profile keycaps you can gently press from underneath on a flat surface, but a cheap puller is worth having. Be careful with long spacebars, which often have multiple stabilizer inserts that can pop out if you pull straight up rather than rocking gently back and forth. Our keyboard guide recommends boards with tool-free stabilisers for this reason.
How do I fix a sticky or scratchy key?
Remove the keycap, pull the switch out of the hot-swap socket, and clean the stem with isopropyl alcohol on a cotton swab. For hot-swap switches you can clean the switch without fully disassembling the board. If the key still sticks, the switch itself is worn and needs replacing, which is trivial on a hot-swappable board and easy on a soldered one.
Is it safe to wash a mechanical keyboard?
Only for the keycaps, and only with care. Most keycaps can be washed in warm soapy water, but do not put switches, a PCB, or a board with a non-detachable USB cable in water. Check the material first: PBT keycaps handle washing well, while ABS keycaps can yellow or degrade with hot water. Our board guides list the material of each pick.
Does cleaning my keyboard improve performance?
It improves feel more than raw performance. A dusty, gummed-up switch causes scratchy feedback and can fail to register a fast press reliably, which does affect gameplay. Cleaning and re-lubricating switches restores the crisp action that made you buy the board in the first place, and keeps the sound consistent over time.
