Symptoms
- Keys feel slower to spring back than they used to
- Visible grime or dust around key edges
- Certain frequently used keys feel worse than others
- No specific spill or liquid incident occurred
Likely causes
- CommonAccumulated dust and skin oil under and around keysNormal daily use gradually deposits oils and debris that affect key feel over time.
- CommonFood crumbs or other debris trapped under keysEating near the laptop is a common source of debris buildup.
- PossibleDried residue from an old, long-forgotten small spillA minor spill from a while back that wasn't fully cleaned can leave lingering residue.
- PossibleWorn key switches feeling sticky due to age rather than dirtAging mechanisms can sometimes feel similar to a dirt-related issue.
What to do
- Turn off the laptop and tilt it at an angle, gently shaking to dislodge loose crumbs and dust from between the keys.
- Use compressed air at an angle to blow out debris from under and around each key.
- For a deeper clean, gently remove a few of the worst-feeling keycaps and clean underneath with a soft brush or lightly dampened cloth.
- Let everything dry fully before reattaching any removed keycaps.
- Clean the whole keyboard regularly going forward to prevent buildup from recurring.
- If keys still feel sticky after a thorough cleaning, the switch itself may simply be worn from age.
Tools and parts
- Compressed air
- Soft brush
- Microfiber cloth

When to call a pro
