Abstract

The present invention relates to methods of using heterogeneous cleaning compositions, particularily for cleaning an article.

Claims (19)

1. A method for cleaning an article, comprising:

providing a heterogeneous cleaning composition, comprising:

more than about 75% active ingredients comprising;

at least about 20 wt. % surfactant;

at least about 20 wt. % sequestrant; and

from about 1 to about 30 wt. % active enzyme composition;

wherein the composition comprises two or more substances that are not evenly dispersed and the composition comprises at least one liquid and at least one powder;

diluting the heterogeneous cleaning composition to form an intermediate homogeneous cleaning composition; and thereafter

adding the intermediate composition to a diluent to form a homogeneous use composition,

wherein the intermediate composition is added to the diluent in the presence of the article to be cleaned to clean the article.

2. The method of claim 1 , wherein the heterogeneous cleaning composition comprises 99% active ingredients.

3. The method of claim 1 , wherein the heterogeneous cleaning composition further comprises at least about 15 wt. % source of alkalinity, at least about 0.5 wt. % antiredeposition agent, and at least about 0.05 wt. % optical brightener.

4. The method of claim 1 , wherein the heterogeneous cleaning composition further comprises only inconsequential amounts of emulsifier, water, dispersant, thickener, binding agent, flow aid, anticaking agent, hydrotrope, or mixtures thereof.

5. The method of claim 1 , wherein the intermediate composition includes from about 1 to about 50 wt. % of the heterogeneous cleaning composition.

6. The method of claim 1 , wherein the homogenous use composition includes from about 0.01 to about 1 wt. % of the heterogeneous cleaning composition.

7. The method of claim 1 , wherein the heterogeneous cleaning composition is in a rigid container.

8. The method of claim 7 further comprising inverting the rigid container prior to diluting the heterogeneous cleaning composition, wherein upon inverting the rigid container a portion of the heterogeneous cleaning composition leaves the rigid container and a portion of the heterogeneous cleaning composition remains in the container.

9. The method of claim 7 , wherein the rigid container is a rigid capsule.

10. The method of claim 1 , wherein the article to be cleaned is an article in an industry selected from the group consisting of the institutional hospitality, food service, and healthcare industries.
