Abstract

This invention includes a cleaning composition, the method of use of the cleaning composition, and a new use of a composition. The composition includes an oxidizing agent with a reduction potential of greater than about 0.1 E°(V) at 25° C., and is devoid of an oxidizing agent with a reduction potential of greater than about 1.5 E°(V) at 25° C. The oxidizing agent may be a salt of a nitrate or nitrite. The method includes applying the composition to a textile and working the composition. The composition may be effective in cleaning urine odors from textiles. The composition may remove odors from textiles without bleaching or discoloring the textile, even if the textile includes natural fibers such as wool.

Claims (11)

1. A method for cleaning a urine odor from a textile, consisting of:

applying a cleaning composition to the textile, wherein the cleaning composition consists of:

an oxidizing agent in aqueous solution with a reduction potential of greater than about 0.1 E°(V) at 25° C.;

a buffering agent; and

devoid of an oxidizing agent with a reduction potential of greater than about 1.5 E°(V) at 25° C.; and

working the cleaning composition into the textile.

2. The method of cleaning a urine odor from a textile of claim 1 , wherein the oxidizing agent has of a reduction potential of less than about 1.0 E°(V) at 25° C.

3. The method of cleaning a urine odor from a textile of claim 2 , wherein the oxidizing agent consists of one selected from the group consisting of: a salt of a nitrate and a salt of a nitrite.

4. The method of cleaning a urine odor from a textile of claim 3 , wherein the oxidizing agent consists of one selected from the group consisting of sodium nitrate and sodium nitrite.

5. The method of cleaning a urine odor from a textile of claim 1 , wherein the buffering agent has an acid dissociation constant of from about 4 to about 6.

6. The method of cleaning a urine odor from a textile of claim 1 , wherein the oxidizing agent consists of a concentration of from about 0.1 to about 2 moles of oxidizing agent per liter of cleaning composition.
