How can I disinfect a comb from lice at home? - briefly
Soak the comb in water heated to at least 130 °F (55 °C) with a few drops of shampoo or a 1:1 mixture of water and white vinegar for 10 minutes, then rinse thoroughly and allow it to air‑dry. This eliminates lice and their eggs without chemicals.
How can I disinfect a comb from lice at home? - in detail
Disinfecting a hair‑comb after a lice infestation requires thorough cleaning and a reliable killing agent. Follow these steps to ensure the tool is free of eggs and nits.
-
Initial rinse – Remove hair and visible debris by running the comb under hot tap water (at least 130 °F / 54 °C). Use a brush or fingernail to scrape off crusted material.
-
Soap wash – Fill a basin with warm water and add a few drops of dish‑washing liquid or a mild antibacterial soap. Submerge the comb for 5 minutes, then scrub each tooth with a stiff brush. Rinse well.
-
Chemical disinfection – Prepare one of the following solutions:
- Bleach mixture: 1 part household bleach (5‑6 % sodium hypochlorite) to 9 parts water. Soak the comb for 10 minutes, then rinse repeatedly with clean water.
- Alcohol dip: 70 % isopropyl alcohol. Immerse the comb for at least 5 minutes; alcohol evaporates quickly, leaving no residue.
- Hydrogen peroxide: 3 % solution, soak for 10 minutes, then rinse.
Choose a method compatible with the comb material (plastic, metal, or wood). Avoid prolonged exposure to bleach on wooden handles.
-
Heat treatment – After chemical disinfection, place the comb in a pot of boiling water for 5 minutes, or run it through a dishwasher on the hottest cycle with a drying phase. Heat kills any surviving eggs.
-
Drying – Lay the comb on a clean towel or paper towel in a well‑ventilated area. Allow it to air‑dry completely before reuse to prevent moisture‑related damage.
-
Verification – Inspect each tooth under bright light. If any nits remain, repeat the washing and disinfection process.
Safety notes
- Wear disposable gloves when handling bleach or alcohol.
- Ensure the area is well‑ventilated to avoid inhaling fumes.
- Do not mix bleach with ammonia or other cleaners.
- Store the disinfected comb in a sealed container until needed.
Applying the above protocol eliminates lice eggs and adults from the comb, making it safe for continued use in a household setting.
