Abstract
Cleaning compositions of surfactant-based products containing one or more alkaline builders for the preparation of liquid cleaning compositions are discussed. The surfactant-based product may be any type of cleaning product based on surfactants. Methods of cleaning a household surface and of making cleaning compositions are also discussed.
