How to Deep Clean a Mechanical Keyboard

Tools & Parts Needed

1

Unplug the Keyboard

Disconnect the keyboard from the PC. Take a photo of the key layout for reference.
2

Remove All Keycaps

Use the keycap puller to remove all keycaps, placing them in a bowl. Pull straight up — do not twist.
3

Soak Keycaps

Soak the keycaps in warm soapy water for 30 minutes to loosen oils and grime.
4

Blow Out the Switch Area

Use compressed air to blow debris from around the switches, holding the can upright.
5

Use 99% isopropyl alcohol on the PCB if needed — anything wetter risks shorts and won’t evaporate fast enough to be safe.

Brush the PCB Surface

Use a dry soft-bristle brush to sweep remaining dust from the PCB and switch housings.
6

Clean Stubborn Stains

Dampen a cotton swab with isopropyl alcohol and clean around switch bases and the PCB surface.
7

Rinse and Dry Keycaps

Drain and rinse the keycaps with clean water. Spread on a towel and let dry for at least 4 hours.
8

Reinstall Keycaps

Once completely dry, press each keycap firmly onto its switch stem using your reference photo.
9

Test All Keys

Plug in and test every key using an online key tester to confirm all switches work correctly.

Never submerge the keyboard body or PCB in water — only the keycaps.

Ensure keycaps are fully dry before reinstalling — moisture can short the switches.

Do not use paper towels on the PCB — they scratch and leave fibres.
