Maintenance
Proper maintenance ensures the longevity and optimal performance of your mechanical keyboard. The two most important points are to keep it away from soot and liquids, and to clean it regularly.
-
Avoid Liquids: Mechanical keyboards are not waterproof. Avoid placing drinks or cups near the keyboard. If liquid accidentally spills onto the keyboard:
- Immediately disconnect the keyboard power.
- Unplug the keycaps to allow the liquid to dry.
- Use the cold air setting of a hairdryer to air dry the keyboard thoroughly.
- Wait a few days before attempting to use it again. Sugary liquids can hinder switch movement if not properly dried.
- Prevent Residue Buildup: Avoid eating directly over the keyboard. Food crumbs and other residues can fall between the keycaps and the panel, potentially damaging the keyboard, affecting its feel, or causing keys to stick over time.
- Regular Cleaning: Regularly clean your keyboard to maintain hygiene and extend its service life. Use a brush or compressed air to remove dust and debris from between the keys.
