Abstract
Abstract The method of making a novel upholstery pad includes the steps of preparing a colloidal suspension containing predetermined amounts of sodium lauryl sulfate, sodium perborate, a degreaser, and a biodegradable soap containing no phosphates. The upholstery pad, which is of multi-ply construction including a terry cloth ply and a velour ply, is immersed in the colloidal suspension at room temperature and is removed and allowed to slowly, partially dry over a predetermined period of time to a damp condition. The pad is then rapidly dried in a drying medium so that the cleaning pad is permeated with a dried cleaning compound that be readily activated by immersing the pad in water.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
123 words
A process of making an upholstery cleaning pad comprising steps of dissolving a predetermined amount of biodegradable soap containing no phosphates in a predetermined volume of boiling water, adding predetermined amounts of sodium lauryl sulfate, sodium perborate and a degreaser to said soap solution to thereby form a colloidal suspension, and thereafter allowing said suspension to cool to room temperature, immersing a fabric pad having a terry cloth ply and a velour ply in said suspension to thoroughly soak the pad with the suspension, removing said fabric pad from the suspension and allowing the pad to slowly partially dry over a predetermined period of time to a damp condition, and thereafter rapidly drying the pad to a dry condition in a drying medium.
Claim 2
Dependent Claim
123 words

Claim 3
Dependent Claim
86 words
A multi-ply upholstery cleaning pad formed of a fabric having a terry cloth ply and a velour ply, said pad having been immersed in a collodial suspension containing predetermination amounts of sodium lauryl sulfate, sodium perborate, the suspension being maintained at room temperature during the time the fabric pad is immersed therein, the fabric pad being allowed to slowly partially dry to a damp condition and thereafter rapidly drying the pad to a dry condition, whereby the cleaning pad is permeated with a dried cleaning compounds.
Claim 4
Dependent Claim
86 words
A multi-ply upholstery cleaning pad formed of a fabric having a terry cloth ply and a velour ply, said pad having been immersed in a collodial suspension containing predetermination amounts of sodium lauryl sulfate, sodium perborate, the suspension being maintained at room temperature during the time the fabric pad is immersed therein, the fabric pad being allowed to slowly partially dry to a damp condition and thereafter rapidly drying the pad to a dry condition, whereby the cleaning pad is permeated with a dried cleaning compounds.
