Do not take your scooter through a car wash or spray with a hose! Remember! This is an electric vehicle and electric and water do not mix! Doing so will CERTAINLY damage the scooter's battery, speed controllers, and other internal components and void your warranty.
To clean your scooter, use a damp sponge or rag with mild cleaners or dish soap. A toothbrush and scrub brush are also handy to get the small crevices on the scooter.
