Maintenance
Cleaning
To maintain optimal performance and hygiene, regularly clean your mouse. Use a soft, dry cloth to wipe down the surface. For stubborn dirt, a slightly damp cloth can be used, ensuring no moisture enters the internal components. Avoid harsh chemicals or abrasive materials.
Replacing Mouse Skates
Over time, the mouse skates (also known as mouse feet or glide pads) on the underside of your mouse may wear out, affecting its glide performance. Your IFYOO G18 comes with replacement skates. To replace them:
- Carefully peel off the old mouse skates.
- Clean the surface where the skates were attached to ensure it's free of residue.
- Peel the backing from the new replacement skates and carefully align them with the designated areas on the mouse's underside.
- Press firmly to ensure proper adhesion.
