## Abstract

A cleaning solution and method of manufacturing a cleaning solution is set forth herein whereby the cleaning solution is environmentally friendly and meets direct release requirements so that the cleaning solution may be directly released into the environment. In one preferred embodiment, the cleaning solution includes water; a thickener; hydrogen peroxide (H2O2) a surfactant; and a pH adjuster.

## Claims

### Claim 1

A cleaning solution comprising:
deionized water;
about 0.01% wt. to 0.5% wt. thickener wherein said thickener is xanthan gum;
about 3% wt. to 8% wt. hydrogen peroxide (H2O2);
a surfactant, wherein said surfactant is a 1-octanesulfonic acid sodium salt at a percent weight range of 1-6% and a C8-C10 alkyl polyglucoside at a percent weight range of 1-8%; and
about 0.01% wt. to 0.99% wt pH adjuster wherein said pH adjuster is sodium metasilicate.

### Claim 2

A cleaning solution comprising:
deionized water;
about 0.01% wt. to 0.5% wt. thickener wherein said thickener is xanthan gum;
about 3% wt. to 8% wt. hydrogen peroxide (H2O2);
a surfactant wherein said surfactant is a C8-C10 alkyl polyglucoside at a percent weight range of 1-8%; and
about 0.01% wt. to 0.99% wt pH adjuster wherein said pH adjuster is sodium metasilicate wherein said pH of said cleaning solution is in the range of 2 to 8.

### Claim 3

A cleaning solution comprising:
deionized water;
about 0.1 to 0.5% wt. xanthan gum;
about 20 to 35% wt. C8-C10 alkyl polyglucoside;
a chelating agent wherein said chelating agent is a methylglycinediacetic acid (MGDA) of about 1 to 3% wt.; and
about 0.01 to 0.06% wt. citric acid.

### Claim 4

A cleaning solution comprising:
deionized water;
about 0.1 to 0.5% wt. xanthan gum;
about 20 to 35% wt. C8-C10 alkyl polyglucoside;
a chelating agent wherein said chelating agent is a trisodium salt of methylglycinediacetic acid (Na3MGDA) of about 1 to 3% wt.; and
about 0.01 to 0.06% wt. citric acid.

### Claim 5

A cleaning solution comprising:
deionized water;
a solvent;
about 1 to 35% wt. C8-C10 alkyl polyglucoside;
a chelating agent;
about 0.5 to 1.5% wt. sodium metasilicate;
about 0.2 to 0.6% wt. citric acid; and
about 0.001 to 0.003% wt. dye.

### Claim 6

A method for manufacturing a cleaning solution, wherein said cleaning solution complies with the EPA's Safer Choice direct release requirements, said method comprising:
providing purified water;
providing a solvent;
providing a surfactant, whereby said surfactant is a C8-C10 alkyl polyglucoside;
providing a chelating agent wherein said chelating agent is a trisodium citrate;
mixing said water and said solvent in a container to create a first mixture;
mixing said surfactant with said first mixture to create a second mixture;
mixing said chelating agent with said second mixture to create a third mixture comprised of said water, said solvent, said surfactant and said chelating agent;
measuring the pH of said third mixture;
providing a pH adjuster and mixing said pH adjuster with said third mixture to create a fourth mixture with a pH in the range of 11.0 to 11.5; and
providing citric acid and mixing said citric acid with said fourth mixture.

### Claim 7 (depends on 6)

The method of claim 6 whereby said solvent is diethylene glycol monobutyl ether C4H9(OCH2CH2)2OH.

### Claim 8 (depends on 6)

The method of claim 6 whereby said solvent is diethylene glycol n-butyl ether C4H9O[C2H4 O]2H.

### Claim 9 (depends on 6)

The method of claim 6 whereby said pH adjuster is sodium metasilicate.

### Claim 10 (depends on 3)

The cleaning solution of claim 3 further comprising:
about 0.001 to 0.003% wt. dye.

### Claim 11 (depends on 4)

The cleaning solution of claim 4 further comprising:
about 0.001 to 0.003% wt. dye.

### Claim 12

A method for manufacturing a cleaning solution, said method comprising:
providing purified water;
providing a thickener whereby said thickener is xanthan gum;
providing hydrogen peroxide (H2O2);
providing a surfactant, wherein said surfactant is a C8-C10 alkyl polyglucoside at a percent weight range of 1-8%; and
providing about 0.01% wt. to 0.99% wt pH adjuster wherein said pH adjuster is sodium metasilicate;
mixing said water and said thickener in a container to create a first mixture;
mixing said hydrogen peroxide with said first mixture to create a second mixture;
mixing with said surfactant with said second mixture to create a third mixture comprised of said water, said thickener, said hydrogen peroxide, and said surfactant;
measuring the pH of said third mixture; and
mixing said pH adjuster with said third mixture to create a fourth mixture with a pH in the range of 2 to 3.

### Claim 13

A method for manufacturing a cleaning solution, said method comprising:
providing purified water;
providing a thickener whereby said thickener is xanthan gum;
providing a surfactant, wherein said surfactant is a C8-C10 alkyl polyglucoside at a percent weight range of 1-35%;
providing a chelating agent wherein said chelating agent is selected from the group consisting of a methylglycinediacetic acid (MGDA) of about 1 to 3% wt. and a trisodium salt of methylglycinediacetic acid (Na3MGDA) of about 1 to 3% wt.;
