Some formulas do not contain large amounts of builders and are suitable for general purpose cleaning including cleaning of glass. Other formulas are concentrated and contain chelating agents (detergent builders) to improve stability of more dilute compositions prepared from the concentrated compositions. Some of the formulas, both dilute and concentrated, possess disinfectant properties.
