beard oil and a paper towel to clean the comb regularly. avoid water as it could cause the wood to crack with time. scrub the comb with a toothbrush to get rid of any dirt caught between the teeth, and again, no water please. wipe the comb then use a little bit of oil and apply all over the comb gently rubbing it in with the paper towel. let it rest overnight. do not keep your comb in places with high levels of moisture. keep the comb dry always and you will get to enjoy your beard comb for a long time.
