Maintenance

• Cleaning: Regularly clean the keyboard to prevent dust and debris buildup. Use a soft, dry cloth for general cleaning. For deeper cleaning, use compressed air to remove particles from between the keycaps.
• Spill Resistance: The keyboard is designed with drain holes to mitigate damage from accidental spills. In case of a liquid spill, immediately disconnect the keyboard from your device, turn it upside down to drain the liquid, and allow it to dry completely before reconnecting.
• Avoid Harsh Chemicals: Do not use abrasive cleaners or solvents, as these can damage the keycaps or the keyboard's finish.
