Method 1: put half a bottle of fine sand or rice in the bottle, then add half a bottle of water and shake it vigorously until the moss is washed clean.

Method 2: Fill the bottle with vinegar, let it stand for a day, and then rinse off the remaining moss in the bottle with water.

Method 3: Add half a bottle of 84 disinfectant to the bottle, cover the bottle cap, and shake it vigorously to make the mossy place touch it. After about one minute, add 200ml water to dilute the original 84 disinfectant, then shake it evenly for about one minute, then rinse it with water several times until it smells 84.
