A spill can affect three things separately: the mouse electronics, the battery/contacts, or the USB/bluetooth receiver. 's cost-based point and 's basic drying suggestion are reasonable first impressions; below are targeted diagnostics and repair steps that go beyond "let it dry" and help decide whether replacement is necessary.

Useful diagnostics (isolates which part failed)

  • Check the receiver in another PC or USB port. If the receiver is detected there, the mouse is likely the problem.
  • Try a known-good wireless (or wired) mouse on the original computer to rule out OS/driver/USB port issues.
  • Confirm the model uses Bluetooth (pair via OS) or a proprietary 2.4 GHz receiver (requires re-pairing or vendor software).
  • Inspect the battery compartment and terminals for white/green corrosion or battery leakage; test battery voltage with a multimeter if available.

Practical salvage and repair tips (if basic drying failed)

  • Disassemble only if comfortable; many shells are held by hidden screws under stickers or the feet. Document screw locations.
  • Clean PCBs and contacts with high‑purity isopropyl alcohol (90%+), a soft brush, and gentle mechanical removal of corrosion (toothbrush, brass brush or pencil eraser). Avoid tap water and avoid abrasive metal tools that can lift traces.
  • Clean the optical sensor window with alcohol and blow out crevices with compressed air. Replace micro-switches or reflow suspect solder joints if competent with soldering.
  • Dry thoroughly with desiccant or warm ventilation (avoid high heat/hairdryers). Reassembly and a test with fresh batteries follow.

When to replace or involve warranty

  • Low-cost mice are usually cheaper to replace. High-end models or units still under warranty merit contacting the manufacturer or a local electronics repair shop before opening the device (disassembly may void warranty).

You should have opened it up right after it happened and dried the circuit board the best you could have. But right now, just pull the batteries out, make sure everything is dry inside and out, and leave it to air dry for a few days. Then try it again, it may work again :)
