Abstract
Abstract A heavy-duty cleaning composition, especially suited for removing soil from baseboards, ceramic tile and walls and other hard-to-get-at areas and for removing wax or finish coatings from floors, baseboards and corners, contains (1) an aqueous solvent system including a water-soluble monobutyl glycol ether organic solvent and (2) a primary amine. Preferably, the composition also contains a water-soluble compatible thickening agent, sufficient compatible surfactant to enhance wetting the surface being cleaned and sufficient compatible water-soluble film-forming resin to inhibit rapid evaporation of the organic solvent and the amine.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
191 words
A sprayable liquid cleaning composition suitable for removing heavy wax build-up and soil from baseboards, cleaning floors and stair areas where floor cleaning machines cannot reach, cleaning soap residue from ceramic tile and grouting and shower areas, and in other areas, consisting essentially of 1. 1-25 parts by weight of a water-soluble monobutyl glycol ether organic solvent; 2. 3-10 parts by weight of a water-soluble primary amine having the formula NH 2 R wherein R is a lower alkyl group having from 1 to 5 carbon atoms, a monohydroxyalkyl group having from 1 to 3 carbon atoms, an aminoalkyl group having from 2 to 3 carbon atoms or hydrogen, the pH of said composition being less than 12 wherein the minimum quantity of said amine and said monobutyl glycol ether organic solvent in said composition is calculated by the expression (x+1)y = 25, where "x" represents the parts by weight organic solvent and "y" represents the parts by weight primary amine per 100 parts by weight of said composition, and where "x" is greater than zero and "y" is greater than 1; and 3. the remainder of 100 parts being water.
