Maintenance
Cleaning the Keyboard
- Use a soft, lint-free cloth slightly dampened with water or a mild cleaning solution to wipe the keycaps and casing.
- Avoid spraying liquids directly onto the keyboard.
- For dust and debris between keycaps, use compressed air.
- To clean under the keycaps, carefully remove them using a keycap puller (not included) and clean the switches and plate.
Keycap and Switch Care
The Node75 features durable PBT keycaps that are resistant to shine and fading. For hot-swappable switches, ensure proper alignment when inserting or removing them to prevent damage to the switch pins or PCB sockets.
