How should a comb be washed to remove lice? - in detail
The comb must be thoroughly decontaminated after each use to eliminate any remaining lice or eggs. Begin by removing hair and debris with a fine‑toothed lice comb, then place the comb in a sink or basin filled with hot water (at least 130 °F/54 °C). Add a small amount of liquid detergent or a mild antiseptic solution, such as a diluted bleach mixture (1 part bleach to 9 parts water) or an enzymatic cleaner, to break down proteinaceous residues.
- Submerge the comb completely and agitate for 30 seconds to release trapped insects.
- Allow the item to soak for 10 minutes, ensuring the temperature remains constant.
- Use a brush with stiff bristles to scrub the teeth and the handle, paying special attention to crevices.
- Rinse under running hot water for at least one minute to flush out loosened debris and cleaning agents.
- Place the comb in a dryer on high heat for 5 minutes or immerse it in a boiling water bath for 3 minutes; both methods guarantee the destruction of any viable lice or nits.
- After drying, store the comb in a sealed, airtight container until the next use.
If a chemical disinfectant is preferred, follow the manufacturer’s recommended contact time, typically 5–10 minutes, before rinsing. Repeating the cleaning cycle after each treatment session prevents re‑infestation and maintains the effectiveness of the comb.
