How to clean dirt off a mouse? - briefly

First, unplug the mouse and remove loose particles with compressed air or a soft brush. Then, wipe the exterior and button gaps with a lint‑free cloth lightly dampened with 70 % isopropyl alcohol, let it dry, and reconnect.

How to clean dirt off a mouse? - in detail

Cleaning a computer mouse requires disassembly (if possible), surface treatment, and reassembly. Follow each step carefully to avoid damage to sensors or circuitry.

  1. Power off and disconnect

    • Unplug a wired mouse or remove batteries from a wireless unit.
    • Place the device on a clean, static‑free surface.
  2. Remove external debris

    • Use a soft brush or compressed air to blow out dust from crevices, scroll wheel, and sensor opening.
    • For stubborn particles, gently tap the mouse upside down over a trash bin.
  3. Prepare cleaning solution

    • Mix a few drops of mild dish soap with warm water.
    • Dampen a lint‑free microfiber cloth; it must be only slightly moist, never dripping.
  4. Wipe the outer shell

    • Rub the cloth over the entire surface, paying special attention to button edges and the scroll wheel.
    • For textured grips, use a cotton swab dipped in the same solution to reach narrow grooves.
  5. Sanitize if needed

    • Apply a small amount of isopropyl alcohol (≥70 %) to a separate cloth and run it over the mouse’s exterior.
    • Allow the alcohol to evaporate completely before proceeding.
  6. Clean the sensor area

    • Hold the mouse upside down; use a dry, soft brush to clear dust from the optical or laser sensor aperture.
    • Do not apply liquid directly to the sensor.
  7. Disassemble (optional for deep cleaning)

    • If the mouse has removable panels, unscrew or slide them according to the manufacturer’s instructions.
    • Clean internal components with a dry brush; avoid contact with circuitry.
    • After cleaning, reassemble securely.
  8. Dry and test

    • Ensure all surfaces are dry; wait at least five minutes before reinserting batteries or reconnecting the cable.
    • Verify cursor movement and button responsiveness.

Regular maintenance—dust removal after each use and a full wipe‑down weekly—prevents grime buildup and extends the device’s lifespan.
