I like yout idea of using lemon i will try it .

• Here is my natural method that im using to clean my comb :

1- Remove any loose hair from the comb by running your fingers or a toothpick through the teeth.

2- Fill a bowl or sink with warm water and add a few drops of mild liquid soap or shampoo. You can also use a mixture of equal parts water and vinegar.

3- Place the comb in the soapy water or vinegar solution and let it soak for about 10-15 minutes. This will help loosen any dirt, oils, or product buildup.

3- Use an old toothbrush or a small brush with soft bristles to scrub the comb gently. Pay close attention to the teeth and any grooves or crevices. This will help remove any remaining debris.

4- Rinse the comb thoroughly under running water to remove any soap residue. Make sure to rinse off all the cleaning solution.

5- Pat dry the comb with a clean towel or let it air dry completely before using it again.

Additional tips:

If your comb is made of a delicate material like wood or certain types of plastic, avoid soaking it for too long or using harsh cleaning agents as they can damage the comb.
For a natural disinfectant, you can add a few drops of tea tree oil or lavender oil to the warm water. These essential oils have antimicrobial properties.
Regularly cleaning your comb will help maintain its hygiene and prevent the transfer of oils and dirt to your hair. Aim to clean it at least once a month or more frequently if it gets visibly dirty or sticky.
Remember to always follow the manufacturer's instructions for cleaning if your comb has any specific recommendations.
