To clean your keyboard, first disconnect it from all power sources. Use a soft, lint-free cloth slightly dampened with water or a mild cleaning solution. For keycaps, you can use the provided keycap puller to remove them and clean them separately. Ensure all components are completely dry before reassembling or reconnecting.

5.2 Battery Care

To prolong battery life, avoid exposing the keyboard to extreme temperatures. If storing for an extended period, charge the battery to approximately 50% and store in a cool, dry place. Recharge periodically if not in use.

5.3 Switch and Keycap Information

The Keychron K6 model K6-P2 features Gateron G Pro Blue Switches, known for their clicky tactile feedback and a lifespan of up to 50 million keystrokes. This specific model is not hot-swappable, meaning the switches are soldered to the PCB and cannot be easily replaced without desoldering.
