ABSTRACT:
A dispenser for and method of dispensing a concentrated cleaning solution from a solid block of a cleaning composition wherein the concentrated cleaning solution is dispensed at a substantially constant concentration during the entire useful life of the solid block of cleaning composition. The dispenser comprises (i) a spray nozzle for directing a uniform dissolving spray onto an exposed surface of the solid block of cleaning composition; and (ii) a spring or hydraulic piston coupled to the nozzle for biasing the nozzle towards the solid block and thereby maintaining a substantially constant distance between the nozzle and the exposed surface of the solid block of cleaning composition even though the exposed surface recedes due to dissolution by the dissolving spray.
