A recharge insert, for use with a spray dispenser device, is made of a matrix material impregnated with a chemical that is dry-to-the-touch and becomes dissolved in solution with a diluent fluid such as water. The recharge insert is formed in an elongated cylindrical shape with a center opening for mounting on the standard plastic downtube of the spray dispenser device. The insert sleeve may be formed with a side slit to open and wrap it around the downtube. When the spray bottle is filled with water, sealed, and shaken, the fluid penetrates into the matrix material, and the chemical composition becomes dissolved in solution, thereby creating a cleaning, sanitizing or disinfectant solution that will remain stable and fully active in use. The matrix material can be mounted on a hollow tubular carrier with lower spacer legs, or affixed to an upper retaining disk that is seated on the container neck for holding the insert clear of the lower intake end of the tube.

[ I claim:] [9.]9. A spray dispenser system comprising a container body for containing diluent fluid therein a spray head removably mounted with a sealing cap to said container body and an elongated down tube connected to said spray head which is inserted into and extends into the container body during use, a recharge insert comprising a matrix material, said matrix comprising (a) natural or synthetic woven or non-woven or knitted fibers or (b) flexible foam material or (c) combinations thereof, impregnated with a chemical composition so that the matrix material remains dry to the touch, said chemical composition being capable of being dissolved in solution with a diluent fluid, said recharge insert being formed in an elongated cylindrical shape with a center opening for mounting on said down tube, said recharge insert having an outer surface which is porous to fluid filled into the container body so that fluid can penetrate into the matrix materials and dissolve the chemical composition impregnated therein into a solution in the fluid, said recharge insert being adapted for removal when spent and being replaced with another impregnated insert.
