1)Water bag disinfection
Add one ounce of household bleach (such as Clorox Regular or Clorox Ultra) to one liter of clean water. After mixing for 10 seconds, pour into a water bag and leave for one night. Finally rinse thoroughly and let dry naturally.
Rinse the water bag with hot soapy water. If the effect is not good, please use 1/4 dry soda and 3/4 water mixed solution, shake for 30 seconds, add 1/4 cup of lemon juice, shake for 10 seconds, loosen the lid, and vent the gas. This was repeated three times to expel the gas as much as possible, and soaked for 20 minutes and then rinsed three times with hot water. Warning: When adding lemon juice to dry soda, it will cause bubbling and negative pressure.
