Foam cannon car
A snow foam cannon, also known as a foam gun or foam lance, is used for the pre-wash of your car. The pre-wash is an essential step for a scratch-free wash. It creates a thick layer of foam over the entire car. The foam helps loosen and safely remove dirt from the car. Simply foam the entire car, let the foam work for a while, and then rinse it off. After that, you can proceed with the hand wash.
