What should I do if water gets into a mouse? - in detail
When a computer mouse contacts liquid, immediate action prevents permanent damage.
- Disconnect power. Remove batteries from a wireless unit or unplug a wired mouse.
- Turn the device upside‑down to drain excess fluid. Gently shake to expel trapped droplets.
- Pat the exterior with an absorbent, lint‑free cloth. Do not rub, as friction may push moisture deeper.
- Disassemble if feasible. For models with removable covers, separate the shell and internal circuit board.
- Place all components on a dry, ventilated surface. Position them on a mesh rack or over a paper towel.
- Allow thorough drying. A minimum of 24 hours is advisable; for larger spills, extend to 48 hours. Use a low‑heat source such as a fan; avoid direct heat that could warp plastic.
- After the drying period, reassemble the mouse and test functionality. If click response is erratic or the sensor fails, the circuit board may require cleaning with isopropyl alcohol (≥ 90 %). Apply the solvent to a cotton swab, wipe the affected area, then let it dry completely before reassembly.
Preventive measures reduce future incidents: keep beverages away from the work area, use spill‑resistant mouse pads, and consider waterproof models.
