Improved hard surface cleaning compositions having an acidic pH provide good removal of soap scum stains, and further feature low levels of irritability to the user. The compositions comprise0.1-10% by weight of an acid sequestrant constituent;0.1-10% by weight of a mixture of hydrophobic and hydrophilic solvents;1-8% by weight of a surfactant and/or hydrotrope constituent;0-20% by weight of one or more optional constituents;the balance to 100% by weight, waterwherein the aqueous hard surface cleaning composition exhibits a pH of 7.0 or less, especially a pH of 5.0 and 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. Processes for the production of the said compositions, as well as methods for their use are also described.
