How to Deep Clean a Mechanical Keyboard (With Keycap Removal)
Steptep 1: Disconnect and Take a Picture for Reference
Unplug your mechanical keyboard from your computer by removing the USB cable. For wireless keyboards, turn it off and remove the batteries if possible.
Disconnecting your keyboard prevents accidental key presses and protects your device during cleaning. Always make sure the keyboard is completely powered off before starting.

Take a Picture for Reference
Before removing any keycaps, take a clear picture of your keyboard layout using your phone. This will help you place each key back correctly during reassembly.
Make sure the photo captures all keys clearly, including:
- Function keys (Print Screen, Scroll Lock, Pause/Break)
- Number pad keys (including multiply and divide)
- Any special or uniquely shaped keys
You can take multiple pictures from different angles for better reference. This step makes reassembly faster, easier, and error-free.
Pro Tip: Use your reference photo while reassembling to avoid confusion and ensure every key goes back in the correct position.
Step 2: Remove Keycaps Carefully
After disconnecting your keyboard, use a keycap puller from your keyboard package to remove keycaps. This careful job prevents damage to keycaps, switches, and stabilizers.
- Start at one end and work your way across the keyboard
- Position the keycap puller evenly around each keycap
- Get a good grip and pull straight up—never twist or angle
- Be gentle to avoid switch damage
- Take your time; there’s no rush
- Place removed keys in a plastic strainer to hold keys for the next step

Handle Stabilizers with Care
Larger keycaps like spacebar and Enter have stabilizers with satellite stems for stability. These bigger keys must be handled with care to reduce the chance of damage. If damaged, hot-swappable keyboards allow easy switch replacement, but non-hot-swappable models require time-consuming soldering to replace the entire switch.
Step 3: Clean the Keyboard Base and Switches
After removing the keycaps, stains inside the keyboard become easier to clean. Follow these steps:
- Wipe the keyboard board using alcohol wipes, focusing on the surface and around each switch
- Brush between switches to remove dust and stubborn debris gently
- Use keyboard cleaning mud to lift dirt from hard-to-reach areas
- These cleaning methods provide deeper access compared to methods without removing keycaps
- Allow the keyboard board to dry completely before reassembling
Step 4: Wash and Dry the Keycaps
Wash the Keycaps
- Fill a basin, sink, bowl, or place a strainer with warm water (never use boiling water as it can damage keycaps)
- Add cleaning agent such as dish soap, detergent, or degreaser to the water
- Mix gently to create a cleaning solution
- Place all keycaps into the water and let them soak for 15-20 minutes
- Use a small brush to scrub difficult parts, cleaning both inside and outside surfaces
- Wash away oils and debris from each keycap thoroughly
- Rinse keycaps under clean warm water to remove all cleaning agent residue


Step 5: Reassemble Your Keyboard
- Double check dryness of all dried keycaps before starting—use a hair dryer on cold air mode if needed to speed up drying and prevent deformation
- Clear the keyboard surface of any remaining debris
- Have your keyboard pictures or photo reference ready for correct key placement
- Take your time with installation according to pictures to avoid mistakes
- Install keycaps one by one, starting with larger keys that have stabilizers
- Center each keycap over the switch stem carefully
- Press all the way down firmly until you hear a satisfying click
- Continue re-seating keys row by row using your photo reference
- This reassemble keyboard process takes a couple of minutes
- Test each key to ensure it’s working properly
- Enjoy your clean keyboard that looks like a brand new keyboard


The entire clean keyboard process is complete! Your keyboard will feel better and last longer with regular maintenance.
