Abstract

A multi-component composition and the process for using same to clean substantially every type of carpet found in residential and commercial use is disclosed. The process employs electrostatic action to remove emulsified soil from the rug surface, said soil having been loosened by the application of the cleaning solution of this invention.

Claims

1. A concentrated composition for use in cleaning rugs and carpets comprising an effective amount of each of:

a. a first detergent soluble in water, said first detergent being selected from the group consisting of sodium alkylnaphthalene and sodium lauryl sulfate wherein said first detergent is used in a concentration of 3% to 7% by volume;

b. a second detergent milder than said first detergent, said second detergent being selected from the group consisting of a sodium C₁₄ -C₁₆ olefin sulfate and a lower alkyl benzene sulfonate wherein said second detergent is used in a concentration of 4% to 8% by volume;

c. an anti-foam agent selected from the group consisting of cocoamide and lauramide wherein said anti-foam agent is used in a concentration of 1% to 3% by volume;

d. a water softener selected from the group consisting of tetrapotassium pyrophosphate and tetrasodium pyrophosphate wherein said water softener is used in a concentration of 8% to 12% by volume;

e. at least one lower alkanol in an amount sufficient to dissolve and loosen potentially sticky substances such as chewing gum, pancake syrup and chocolate sauce;

f. a low foam surfactant consisting of non-ionic polyglycol wherein said low foam surfactant is used in a concentration of 2% to 10% by volume;

g. an optical brightener wherein said optical brightener is used in a concentration of 0.05% to 0.2% by volume;

h. at least one thickening agent wherein said thickening agent is used in a concentration of 0.05% to 0.2% by volume;

i. at least one electrostatic conductant selected form the group consisting of aminoethylacrylate-phosphate, oblique acrylate copolymer and alkyl dimethylbenzyl ammonium chloride wherein said electrostatic conductant is used in a concentration of 0.5% to 1.5% by volume;

j. tannin in a concentration of 2% to 6% by volume; and

k. water in an amount sufficient to make a total volume of 1 gallon of the concentrated composition.
