First, soak the wooden comb in water briefly. Then, apply some shampoo on the comb and gently brush it back and forth with a soft - bristled toothbrush. Finally, rinse it thoroughly with clean water. Keep the soaking time short to prevent the comb from warping due to water absorption. You can blot the water off the comb with a paper towel first and then dry it in a cool, ventilated place.
Use a toothpick to pick out all the dirt inside the wooden comb. You can wipe off some debris with a cotton swab. This process may take some time, so you need to be patient.
