## Abstract

A cleaning composition for treating and removing stains from a non-porous surface has one or more salts, such as quaternary ammonium salts, sulfates and chlorides, a chelator and a dispersant, dissolved in an aqueous solution of alcohol. The preferred salts are myristyltrimethylammonium bromide and benzethonium chloride, the chelator is tetrasodium salt ethylenediamine of tetraacetic acid, and the dispersant is polyvinyl alcohol. The cleaning composition is incorporated into a product, which has a non-woven polyester carrier impregnated with the cleaning composition.

## Claims

### Claim 1

A cleaning composition, comprising:
between about 0.4% and 4.2% by volume of each myristyltrimethylammonium bromide, benzethonium chloride and tetrasodium salt ethylenediamine of tetraacetic acid, and between about 0.4 to about 1.0% by volume of polyvinyl alcohol, dissolved in water.

### Claim 2

A cleaning composition, comprising myristyl trimethylammonium bromide, benzethonium chloride, tetrasodium salt ethylenediamine of tetraacetic acid, and polyvinyl alcohol, dissolved in water.

### Claim 3

A cleaning composition, comprising:
between about 0.4% and 4.2% by volume each myristyltrimethylammonium bromide, benzethonium chloride and tetrasodium salt ethylenediamine of tetraacetic acid, and between about 0.4 to about 1.0% by volume of polyvinyl alcohol, dissolved in water and having a concentration of solids more than 50%.

### Claim 4

A method of treating stains on a non-porous surface, the method comprising the steps of:
applying to the stained surface a pre-determined amount of a cleaning mixture comprising myristyl trimethylammonium bromide, benzethonium chloride, tetrasodium salt ethylenediamine of tetraacetic acid, and polyvinyl alcohol, dissolved in water and having a pre-determined concentration of solids to form a viscous mixture with a specific gravity of 0.995 g/ml of solution.

### Claim 5

A method of treating stains on a non-porous surface, the method comprising the steps of:
applying to the stained surface a pre-determined amount of a cleaning mixture comprising between about 0.4% and 4.2% by volume each myristyltrimethylammonium bromide, benzethonium chloride and tetrasodium salt ethylenediamine of tetraacetic acid, and between about 0.4 to about 1.0% by volume of polyvinyl alcohol dissolved in water.

### Claim 6 (depends on 5)

The method of claim 5, further comprising the step of allowing said mixture to dry and then rubbing said surface to remove the dried mixture.

### Claim 7

A device for removing stains from a non-porous surface, comprising:
a flexible porous carrier impregnated with a cleaning composition, which comprises between about 0.4% and 4.2% by volume each myristyltrimethylammonium bromide, benzethonium chloride and tetrasodium salt ethylenediamine of tetraacetic acid, and between about 0.4 to about 1.0% by volume of polyvinyl alcohol dissolved in water to form a viscous mixture having a specific gravity of 0.995.

### Claim 8 (depends on 7)

The device of claim 7, wherein said carrier is made from a non-woven polyester fabric.

### Claim 9 (depends on 7)

The device of claim 7, wherein said cleaning composition has a concentration of solids per volume of water added in excess of 50%.
