The reasons why there is only half a bottle of dish soap may be as follows:

1. During the filling process, the bottle mouth of the dish soap may not be completely sealed, causing liquid leakage. .

2. Liquid leakage may be caused by bumps or temperature changes during transportation.

3. In addition, it may be that the dishwashing liquid was opened or contaminated due to human factors or improper storage conditions during the sales process.

In order to solve this problem, it is recommended that when purchasing dish soap, you choose a manufacturer with a good brand reputation and advanced bottle sealing technology, and take appropriate measures during transportation and storage to ensure product quality. .
