Care of your Osprey Hydraulics Bladder.
- Empty and rinse after use.
- Drain and air again before storing.
- To clean, use hot soapy water and rinse thoroughly with hot water.
- For tough cleaning jobs, add 1/4 cup of baking soda to 3/4 water and shake for 30 seconds. Add 1/4 cup of lemon juice, shake for 10 seconds and vent holding away from face. Repeat 3 times. Expel as much air as possible then leave for 20 minutes. Rinse with hot water. Warning: Adding lemon juice to baking soda makes it fizz so don't leave your bladder unattended for too long.
