Abstract
A hard surface cleaning solution having improved cleaning and descaling properties. The cleaning solution includes the following components: a first organic acid, a second organic acid, a surfactant, a solvent and a diluent. The first organic acid is a carboxylic acid, preferably lactic acid, while the second organic acid is also a carboxylic acid, preferably gluconic acid. The surfactant is selected from the group consisting of amine oxides, preferably lauramine oxide. The solvent may be an alkoxylated alcohol, preferably selected from the propylene glycol ether class of compounds.

A hard surface cleaning solution for descaling calcium, lime and rust, consisting essentially of:
- a first organic acid comprising a carboxylic acid selected from the group consisting of lactic acid, glycolic acid, formic acid, citric acid and acetic acid;
- a second organic acid comprising a carboxylic acid different from the first organic acid and selected from the group consisting of gluconic acid, glycolic acid, formic acid, citric acid and acetic acid;
- a surfactant selected from the group consisting of amine oxides;
- a solvent selected from the group consisting of ether alcohols;
- and
- a diluent;
- wherein the solution has a pH ranging from about 2.0 to about 2.4;
- wherein the solution effectively descales calcium, lime and rust;
- and
- wherein the surfactant does not contain salt in an amount sufficient to materially affect the pH of the hard surface cleaning solution.
A hard surface cleaning composition for descaling calcium, lime and rust, consisting essentially of:
- lactic acid, in an amount of about 12 wt. % to about 18 wt. % of the active cleaning composition;
- gluconic acid, in an amount of about 2.5 wt. % to about 3.75 wt. % of the active cleaning composition;
- an amine oxide, in an amount of about 1.5 wt. % to about 3.25 wt. % of the active cleaning composition;
- dipropylene glycol n-butyl ether, in an amount of about 0.5 wt. % to about 3.0 wt. % of the active cleaning composition;
- deionized water, in an amount of about 72.0 wt. % to about 83.50 wt. % of the active cleaning composition;
- wherein the composition has a pH ranging from about 2.0 to about 2.4;
- wherein the composition effectively descales calcium, lime and rust;
- and
- wherein the surfactant does not contain salt in an amount sufficient to materially affect the pH of the hard surface cleaning solution.
