ABSTRACT:
Improved hard surface cleaning compositions having an acidic pH, providing good removal of soap scum stains, and further feature low levels of irritability to the user. The compositions comprise about 0.1-10% by weight of an acid sequestrant constituent; about 0.1-10% by weight of a mixture of hydrophobic and hydrophilic solvents; about 0.001-1% by weight of a single constituent which exhibits both anionic surfactant and hydrotrope properties; about 0-20% by weight of one or more optional constituents; the balance to 100% by weight of water, wherein the aqueous hard surface cleaning composition exhibits a pH of 7 or less, especially a pH of about 5 or less. Although acidic, the improved hard surface cleaning compositions feature low irritability to the eyes and skin of consumers. The compositions also provide disinfecting effects.
