Score a post work endorphin rush... load up the Viper and saddle up for a quick blast around the hills. This baby lets you cart around a genuine 2.5 litres of go-juice for hands-free refuelling while you keep the pedal to the metal.
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.
