5. Maintenance

5.1 Cleaning

To clean the keycaps, gently pull them off using a keycap puller (if provided) or by hand.
Wipe the keycaps with a damp cloth and mild soap, then dry thoroughly before reattaching.
Use compressed air to remove dust and debris from between the switches.
Wipe the keyboard frame with a soft, dry cloth.

5.2 Switch Replacement

Thanks to the hot-swappable design, you can easily replace individual switches without soldering. Use a switch puller to carefully remove the existing switch. Align the pins of the new switch with the holes on the PCB and press firmly until it clicks into place. Ensure the pins are not bent during insertion.
