Maintenance

To ensure the longevity and optimal performance of your BlueFinger K98 keyboard, follow these maintenance guidelines:

• Cleaning: Use a soft, dry cloth to wipe down the keyboard surface. For deeper cleaning, gently remove keycaps (if applicable and designed for removal) and use compressed air to clear debris from underneath. Avoid using harsh chemicals or abrasive materials.
• PBT Keycaps: The durable PBT keycaps are wear-resistant and designed to prevent legends from fading. Regular cleaning will maintain their appearance.
