1, First, choose fresh and disease-free loofah to ensure the quality of loofah water. Before extracting the loofah water, make sure that the surface of the loofah is clean and free of impurities and dirt. Cut the loofah into small pieces and extract the loofah water with a juicer or a press tool. Ensure that no chemicals are added in the extraction process.

2. Secondly, use clean gauze or filter to filter the loofah water to remove the residual solid impurities. Pour the loofah water into a clean glass bottle or plastic bottle, and disinfect the bottle with an ultraviolet sterilizer or boiling disinfection method.

3. Finally, seal the sterilized loofah water to prevent air from entering. You can use sealed bottles or bags. Store the sealed loofah water in a cool, dry and dark place to avoid direct sunlight and temperature changes.
