Abstract

The present invention relates to stable polymer systems comprising anionic and modified polyamine polymers. When such polymer systems are employed in cleaning compositions, such cleaning compositions exhibit unexpectedly improved anti-soil re-deposition and situs whitening capabilities.

Claims

1. A method of cleaning a situs comprising contacting said situs, or a soiled portion thereof, with the cleaning composition of claim 3 or a diluted solution comprising the cleaning composition of claim 3 and then optionally washing, followed by optionally rinsing said situs.
