Stable mildly acidic aqueous polishing cleanser and preparation thereof

The process for preparing a stable mildly acidic aqueous polishing cleanser for removing stains from hard surfaces comprising by weight from about 8 to 20% of a polishing agent having an average particle size of about 2 to 4 microns, from about 1 to 5% of a nonionic surfactant, from about 1 to 2.25% of a thickening agent consisting of smectite clay and xanthan gum in a weight ratio of about 2:1 respectively, from about 1.25 to 6.25% of an oxalate salt selected from ammonium bioxalate or a mixture of ammonium bioxalate and ammonium oxalate, and from about 68 to 89% of water, said process which comprises adding successively with stirring or mixing to the water heated to about 110.degree.-150.degree. F. the polishing agent, the smectite clay, the xanthan gum and the nonionic surfactant, cooling the mixture to at least below 80.degree. F., then adding successively with stirring or mixing about 1 to 5% by weight of oxalic acid as its dihydrate and about 1.2 to 1.6 mole equivalent of ammonium hydroxide per mole of oxalic acid, and, if necessary, adjusting the pH to about 3.0 to 4.5.

The process for preparing a stable mildly acidic aqueous polishing cleanser for removing stains from hard surfaces comprising by weight from about 8 to 20% of a polishing agent having an average particle size of about 2 to 10 microns and having a particle size distribution from about 1 to 40 microns, from about 1 to 5% of a nonionic surfactant, from about 1 to 2.25% of a selected thickening agent, about 1.25 to 6.25% of an oxalate salt selected from ammonium bioxalate or a mixture of ammonium bioxalate and ammonium oxalate, and, from about 68 to 89% of water, said process which comprises adding successively with stirring or mixing to the water, smectite clay, xanthan gum, the nonionic surfactant, about 1 to 5% by weight of oxalic acid as its dihydrate about 1.2 to 1.6 mole equivalent of ammonium hydroxide per mole of oxalic acid, if necessary adjusting the pH to about 3.0 to 4.5, and, the polishing agent.
