ABSTRACT:
A hard surface cleaning solution having improved cleaning and descaling properties. In one formulation, the cleaning solution comprises a first organic acid, a second organic acid, a surfactant, a solvent and a diluent. The first organic acid is a carboxylic acid preferably comprising lactic acid, while the second organic acid is a carboxylic acid preferably comprising gluconic acid. The surfactant is selected from the group consisting of sultaines, betaines and amino propionates. The solvent is a an alkoxylated alcohol preferably selected from the propylene glycol ether class of compounds. In a second formulation, the cleaning solution comprises a first organic acid, a surfactant, a solvent and a diluent. The first organic acid is a carboxylic acid preferably comprising lactic acid, while the surfactant is selected from the group consisting of sultaines, betaines and amino propionates and the solvent is a an alkoxylated alcohol preferably selected from the propylene glycol ether class of compounds. The cleaning solutions may also include other components such as colorants, fragrance enhancers, corrosion inhibitors, nonionic surfactants or other additives.
