Abstract

The present invention relates to liquid acidic hard surface cleaning composition which are effective against common stains encountered on hard surfaces, methods for cleaning such hard surfaces as well as methods for the manufacture of said liquid acidic hard surface cleaning compositions.

Claims (12)

1. An acidic hard surface cleaning composition consisting of:

in excess of 1% wt, to 30% wt. of a surfactant system which is at least two different nonionic surfactants,

0.01 to 10% wt. of a volatile paraffinic hydrocarbon having a vapor pressure of 0.2 mmHg or more at 20° C.;

an acid constituent which is one or more organic or inorganic acids in an amount effective to impart an acidic pH to the composition;

an amphiphilic solvent constituent selected from glycol ethers;

at least 85% wt, water,

optionally, one or more constituents selected from the group consisting of: coloring agents and fragrances,

characterized in that the composition exhibits self-induced movement when the composition is applied as a film or laminar layer onto a hard surface.

2. An acidic hard surface cleaning composition according to claim 1 , wherein the acid constituent is at least 2 different acids.

3. An acidic hard surface cleaning composition according to claim 1 , wherein the volatile paraffinic hydrocarbon having a vapor pressure of 0.2 mmHg or more at 20° C. is present in an amount from 2 to 10 wt %.

4. An acidic hard surface cleaning composition according to claim 1 wherein the amphiphilic solvent is propylene glycol n-propyl ether.

5. A method of cleaning hard surfaces comprising the step of providing a cleaning effective amount of an acidic hard surface cleaning composition according to claim 1 to the hard surface in need of cleaning.
