How to treat a comb for lice? - in detail

Proper sanitation of a lice comb is essential for preventing reinfestation. The device must be disinfected after each use and stored in a clean environment.

The most reliable method involves thermal and chemical treatment:

  • Rinse the comb under running water to remove visible debris.
  • Submerge the comb in boiling water (100 °C) for at least 5 minutes. Metal combs tolerate heat better than plastic; for plastic, use water at the highest safe temperature (approximately 80 °C) and extend the soaking time to 10 minutes.
  • Transfer the comb to a solution of 70 % isopropyl alcohol. Immerse for 10 minutes, then rinse thoroughly with clean water.
  • For additional disinfection, prepare a dilute bleach solution (1 part household bleach to 9 parts water). Soak the comb for 5 minutes, then rinse until the bleach odor disappears.
  • Allow the comb to air‑dry on a clean towel or paper towel. Avoid using cloths that may retain moisture.

Alternative approaches include:

  • Placing the comb in a dishwasher’s sanitize cycle (top rack, no detergent).
  • Using a UV‑light sanitizer designed for small personal items, following the manufacturer’s exposure time.

Maintenance recommendations:

  • Inspect the comb after each cleaning session; replace if teeth become bent or corroded.
  • Store the dry comb in a sealed plastic bag or a dedicated, lint‑free container.
  • Perform a full cleaning routine at least once a week during an active infestation, and after the infestation has cleared.

These procedures eliminate viable lice and nits, ensuring the comb does not serve as a reservoir for future outbreaks.
