Maintenance
Cleaning Your Keyboard
To ensure the longevity and optimal performance of your Newmen GM681 keyboard, regular cleaning is recommended.
- Dust Removal: Use a can of compressed air to blow away dust and debris from between the keycaps. Hold the can upright and spray in short bursts.
- Surface Cleaning: Gently wipe the keycaps and keyboard surface with a soft, lint-free cloth slightly dampened with water or a mild, non-abrasive cleaning solution. Avoid excessive moisture.
- Deep Cleaning (Keycaps): For a more thorough clean, you can carefully remove the keycaps using a keycap puller (not included). Wash the keycaps in warm, soapy water, rinse thoroughly, and ensure they are completely dry before reattaching them to the switches.
Caution: Do not immerse the keyboard in any liquid. Avoid using harsh chemicals or abrasive materials, as they may damage the keyboard's finish or components.
