Symptoms
- Keys feel soft or slow to spring back compared to before the spill
- Typing feels inconsistent across different keys
- Residue or stickiness can be felt around key edges
- Some keys feel worse than others depending on where the liquid pooled
Likely causes
- CommonResidual liquid or sugar residue still present under the affected keysEven after visible liquid dries, a film can remain that changes how the switch feels.
- CommonSwitch mechanism partially gummed up, preventing a full, crisp travelSticky residue changes the mechanical feel of a scissor or butterfly switch.
- PossibleMoisture still trapped inside the switch mechanismSome liquid can remain trapped in tight mechanical spaces longer than expected.
- Less commonEarly corrosion beginning to affect the key's mechanical partsMore likely if the spill wasn't cleaned soon after it happened.
What to do
- Power off the laptop and remove the affected keycaps carefully with a small flat tool.
- Clean the exposed switch and the keycap's underside with a cloth lightly dampened with isopropyl alcohol.
- Use a cotton swab to reach into tighter areas of the switch mechanism.
- Let everything dry completely, ideally for several hours, before reattaching keycaps.
- Test each cleaned key for a crisp, consistent feel after reassembly.
- If mushiness persists after cleaning, the switch mechanism itself may have been damaged and need replacement.
Tools and parts
- Small flat plastic tool
