Abstract
The present invention relates to cleaning compositions comprising conversion agents and methods of using them. The conversion agents of the present invention comprise water insoluble compounds such as metal oxides, metal hydroxides, and combinations thereof. The compositions can be substantially free of a builder, e.g., a chelating agent, sequestrant, and/or threshold agent, while still achieving effective soil removal.
