Maintenance
Cleaning Your Keyboard
Regular cleaning helps maintain the performance and appearance of your keyboard. Due to its IP32 water and dust resistance, minor spills are less of a concern, but proper cleaning is still recommended.
- Dust Removal: Use a can of compressed air to blow away dust and debris from between the keys.
- Surface Cleaning: Dampen a soft, lint-free cloth with a small amount of water or a mild, non-abrasive cleaning solution. Gently wipe the keycaps and the keyboard surface. Avoid excessive moisture.
- Stubborn Stains: For more stubborn stains, a cotton swab lightly dampened with isopropyl alcohol can be used on keycaps, but avoid direct contact with the keyboard's internal components.
- Drying: Ensure the keyboard is completely dry before reconnecting it to your computer or using it.
Do not immerse the keyboard in water or use harsh chemicals.
