The cleaning steps are as follows:

1. Remove the trademark: Generally, newly purchased bamboo chopsticks will have a trademark. You can use the place with the trademark to blow air to soften the trademark after it is heated. Very easy to peel off.

2. Remove thorns: Bamboo chopsticks are made of bamboo, and there will be fine thorns on them. You need to clean the fine thorns on the surface of the chopsticks to ensure that the surface of the chopsticks is smooth and avoid scratching yourself.

3. Remove odor: Put the newly purchased bamboo chopsticks into a device filled with vinegar for half an hour, which can effectively remove the odor on the chopsticks.

4. Disinfection: Wash the chopsticks, then clean them with detergent, and then boil them in boiling water for half an hour to effectively remove dust and bacteria on the surface of the chopsticks.
