1. First put the bought soles into a clean basin, and then put the clean water into the basin, so that the clean water will not flow through the soles.

2. Add a little edible salt to the pot with bamboo spatula. The salinity of water is just like the salt water we usually drink. Only when this salinity is reached can the bamboo shovel spit sand.

3. After adding edible salt, add a few drops of sesame oil. After adding sesame oil, a few hours later, you can see a lot of dirty things at the bottom of the basin.

In the process of washing, we have to change the water many times, just keep changing the water for the first time.

Wash it several times according to the above method, and the bamboo razor will be clean. If you want to judge whether the bamboo razor is clean, you can squeeze its straw. If there is no sand, it means it is clean.
