A cleaning composition that can discharge the color of blood, menstrual fluids, or other organic stains is provided. In particular, the present invention achieves a balance between control of unwanted liquid spreading by lateral wicking on a stained textile fabric to lessen the size of wet spots and maintaining the cleaning efficacy of the composition by means of specific kinds of thickening agents. The composition includes an oxidizing agent such as peroxides, a cell-lysing agent, a chelating agent, an antioxidant, a thickener, and other optional ingredients that are selectively employed to achieve an aqueous based composition that exhibits good shelf stability and stain removal properties. The thickening agent may include a cellulosic or clay material, starch, gum, fatty acid, fatty alcohol, hydrophilic colloidal particles, polyoxyethylene glycol or polyoxyethylene glycol derivatives including fatty acid esters and ethers, or a combination thereof.

1. A stain-removing kit for pre-treating a stain comprising: a number of absorbent substrates that are adapted to draw moisture away from a treated stain area; a dispenser containing a stain-discharging composition with an aqueous or polar solvent medium; and a stain agitating device, which is configured either separately from or as an integrated part of said dispenser; wherein the composition contains at least one peroxide in an amount of from about 0.1 wt. % to 0.68 wt. %, and also at least one cell lysing agent in an amount from about 0.1 wt. % to 0.9 wt. %, a chelating agent, and an antioxidant, wherein the antioxidant includes tocopherol or a derivative thereof, polar solvent, and a non-acrylate thickening agent in an amount from about 0.001 wt. % to about 10 wt. %, wherein the non-acrylate thickening agent is a clay, starch, cellulose, gum, or a combination thereof, and wherein the composition has a viscosity of from about 10 centipoise to about 600 centipoise, determined at ambient temperature and a shear rate of 5 sec−1. 2. The kit according to claim 1, wherein said polar solvent is water. 3. The kit according to claim 1, wherein said cell-lysing agent is a surfactant. 4. The kit according to claim 1, wherein said chelating agent includes an aminocarboxylic acid, a salt of an aminocarboxylic acid, or a combination thereof. 5. The kit according to claim 1, wherein said solvent medium is in the form of either a liquid, gel, or semi-solid. 6. The kit according to claim 1, wherein said absorbent substrates are formed from at least one or a combination of the following: a paper toweling material, an absorbent cellulose-based fabric, an absorbent sponge or foam, a nonwoven fabric basesheet material, or a superabsorbent material. 7. The kit according to claim 1, wherein said absorbent substrates are formed from at least one of the following or combinations thereof in a laminated form: a) co-form or hydroentangled substrate, b) a cellulose airlaid fabric with about 50-60% of a superabsorbent homogeneously mixed therein, c) a cotton cellulose spunlace fabric, or d) cotton quilted squares. 8. The kit according to claim 1, wherein the composition contains from about 0.1 wt. % to about 10 wt. % of the chelating agent, from about 0.0005 wt. % to about 5 wt. % of the antioxidant, and from about 50 wt. % to about 99.9 wt. % of the polar solvent. 9. The kit according to claim 1, wherein the peroxide is hydrogen peroxide. 10. The kit according to claim 1, wherein the composition has a viscosity of from about 75 centipoise to about 600 centipoise. 11. A stain-discharging composition comprising: at least one peroxide in an amount of from about 0.1 wt. % to 0.68 wt. %, from about 0.1 wt. % to 0.9 wt. % of at least one cell lysing agent, from about 0.1 wt. % to about 10 wt. % of at least one chelating agent, from about 0.0005 wt. % to about 5 wt. % of at least one antioxidant, wherein the antioxidant includes tocopherol or a derivative thereof, from about 0.001 wt. % to about 10 wt. % of at least one non-acrylate thickening agent, and from about 50 wt. % to about 99.9 wt. % of at least one polar solvent, wherein the non-acrylate thickening agent is a clay, starch, cellulose, gum, or a combination thereof, and wherein the composition has a viscosity of from about 10 centipoise to about 600 centipoise determined at ambient temperature and a shear rate of 5 sec−1. 12. The composition according to claim 11, wherein the chelating agent includes an aminocarboxylic acid, a salt of an aminocarboxylic acid, or a combination thereof. 13. The composition according to claim 11, wherein the chelating agent includes ethylenediaminetetraacetic acid (EDTA), a salt of ethylenediaminetetraacetic acid (EDTA), or a combination thereof. 14. The composition according to claim 11, wherein the chelating agent constitutes from about 0.1 wt. % to about 5 wt. % of the composition. 15. The composition according to claim 11, wherein the antioxidant includes vitamin E acetate, vitamin E linoleate, vitamin E nicotinate, vitamin E succinate, or a combination thereof. 16. The composition according to claim 11, wherein the antioxidant constitutes from about 0.001 wt. % to about 1 wt. % of the composition. 17. The composition according to claim 11, wherein the peroxide is hydrogen peroxide. 18. The composition according to claim 11, wherein the composition has a viscosity of from about 75 centipoise to about 600 centipoise.
