Dispensing techniques utilize existing fluid to dispense a solid block of chemical product concentrate. The solid chemical product concentrate may include, for example, detergents, disinfectants, sanitizers, rinse agents, or other cleaning agents. The dispenser monitors and controls the concentration of the chemical product in a use solution. When the concentration of the use solution falls outside of a target range, the dispenser routes existing fluid from within the system to the dispenser, where it interacts with and dispense a solid chemical product concentrate, thus raising the concentration of the chemical product in the use solution. In a dishmachine application, the existing fluid may include post wash or rinse fluid from the dishmachine, or may include use solution from a sump, tank, or other use solution storage container. 1. A system comprising:a chemical product dispenser having a housing sized to receive a chemical product in the form of a solid chemical product concentrate, the housing further including an inlet by which recycled fluid from a cleaning apparatus enters the housing and an outlet by which a dispensed solution, formed by contact of the recycled fluid with the solid chemical product concentrate, exits the housing and is directed to a sump containing a use solution;a fluid directing device; anda controller that determines the concentration of the chemical product in the use solution and electronically controls the fluid directing device to direct the recycled fluid from the cleaning apparatus to the sump if the concentration of the chemical product in the use solution satisfies a target concentration, and to direct the recycled fluid from the cleaning apparatus to the inlet of the dispenser if the concentration of the chemical product in the use solution does not satisfy the target concentration, such that the recycled fluid contacts the solid chemical product concentrate to form the dispensed solution, the dispensed solution exits the ...
