Nettoyage du clavier
- Élimination de la poussière : Regularly use compressed air to blow away dust and debris from between the keycaps.
- Nettoyage des touches : For general cleaning, wipe the PBT keycaps with a soft, slightly damp cloth. Avoid using harsh chemicals or abrasive materials, as these can damage the keycap surface or legends.
- Nettoyage en profondeur (facultatif) : For a more thorough clean, keycaps can be carefully removed using a keycap puller (not included) and washed with mild soap and water. Ensure keycaps are completely dry before reattaching them.
