Abstract

Systems and methods are provided for removing a stain from a surface. A first solution is applied to the stain, wherein the first solution comprises a combination of an ammoniated substance such as ammonium hydroxide and an alcohol such as isopropanol. A second solution is then applied to the stain treated with the first solution, wherein the second solution comprises between approximately 6% and approximately 15% hydrogen peroxide.

Claims (37)

1. A stain removal system, comprising:

a container holding:

a first solution comprising:

between approximately 3% and approximately 9% ammonium hydroxide; and

between approximately 70% and approximately 98% isopropanol; and

a second solution comprising:

between approximately 6% and approximately 15% hydrogen peroxide;

wherein the solutions are mixed to form a single solution.

2. The stain removal system of claim 1 , further comprising a stabilizing agent.

3. The stain removal system of claim 1 , wherein the container has a volume gauge arranged thereon.

4. The stain removal system of claim 1 , further comprising a third container in which a portion of the first solution and a portion of the second solution are mixed to form the single solution.

5. The stain removal system of claim 4 , wherein the first, second, and third containers comprise flexible plastic.

6. The stain removal system of claim 4 , further comprising a stabilizing agent in the third container.

7. A stain removal composition, consisting essentially of:

a first solution consisting essentially of 3-9% of an ammoniated substance and 70-98% of an alcohol; and

a second solution consisting essentially of 6-15% of a peroxide;

wherein the first solution and the second solution are combined to form a single solution.

8. The stain removal composition of claim 7 , wherein the ammoniated substance is ammonium hydroxide.

9. The stain removal composition of claim 8 , wherein the alcohol is isopropyl alcohol.

10. The stain removal composition of claim 9 , wherein the peroxide is hydrogen peroxide.

11. The stain removal composition of claim 7 , further comprising a stabilizing agent.

12. A method of removing a stain from a surface, the method comprising:

providing a first solution, the first solution comprising:

between approximately 3% and approximately 9% ammonium hydroxide; and

between approximately 70% and approximately 98% isopropanol; and

providing a second solution, the second solution comprising:

between approximately 6% and approximately 15% hydrogen peroxide;

mixing the first solution and the second solution to form a combined solution; and

applying the combined solution to the stain.

13. The method of claim 12 , further comprising allowing the stain to dry before applying the combined solution.

14. The method of claim 13 , wherein allowing the stain to dry comprises allowing the stain to dry for at least 7 days.

15. The method of claim 12 , wherein the method does not include any rubbing, scrubbing, or scraping after the first and second solutions are applied.

16. The method of claim 12 , further comprising:

applying a second application of the combined solution.

17. The method of claim 12 , wherein the stain is an organic stain.

18. The method of claim 12 , wherein the surface is a natural or synthetic carpet surface.

19. The method of claim 12 , wherein the first solution and the second solution are mixed immediately prior to application of the combined solution.
