An apparatus configured for mixing and distributing a cleaning solution for use in a vehicle washing system. A container includes a cavity configured to receive the cleaning solution. A supply device for providing an aqueous solution includes a control mechanism for determining the level of aqueous solution in the container. One or more conduits in fluid communication with the supply device supply the aqueous solution to the container. A distribution device in communication with the cavity of the container is configured to remove the aqueous solution from the container for distribution to the vehicle washing system. The one or more conduits include one or more injection inlets for supplying the aqueous solution under pressure to dilute an additive placed in the container with the aqueous solution to create the cleaning solution.
