A jointed car wash gravity hose boom is provided. The jointed car wash gravity hose boom has a first frame unit and a second frame unit secured together at a joint and wherein the first frame unit has a lower support beam and an upper support beam wherein the lower support beam extends upward at approximately a ten to forty degree angle. A hose supplying air, water, soap, wax, foam, tire shine or other liquids for washing a car is secured to the second frame and extends downward at the distal end of the second frame. When the hose is pulled into place by a user, the first frame and second frame generally extend at the joint and allow the user to move the hose around a car wash bay. When relaxed, the jointed car wash gravity hose boom folds at the joint and automatically moves parallel to a wall by gravity.
