THE INVENTION PROVIDES A HARD SURFACE CLEANING COMPOSITION OF PH 3-11 COMPRISING:A)1-30NONIONIC SURFACTANT,B)0.005-5OF A WATER SOLUBLE, ANIONIC POLYMER HAVING AN AVERAGE MOLECULAR WEIGHT OF LESS THAN 1000000, SAID POLYMER BEING FREE OF QUATERNARY NITROGEN GROUPS, WHEREIN, THE RATIO OF POLYMER:NONIONC IS 0.1:1 OR LESS, AND,C)0.005-5OF A CATIONIC SURFACTANT.IT IS BELIEVED THAT IN THE PRESENCE OF THE CATIONIC SURFACTANT, NEGATIVELY CHARGED (I.E. CARBOXYLIC DISSOCIATED) POLYMER CAN INTERACT WITH THE CATIONIC SURFACTANT AND THE NONIONIC SURFACTANT TO FORM A THREE-COMPONENT COMPLEX WHICH DEPOSIT THE NONIONIC SURFACTANT UPON THE SOIL AND/OR SURFACE BEING CLEANED. WHILE THE MECHANISM IS NOT ENTIRELY CLEAR, THIS MAY POSSIBLY BE DUE TO THE INTERACTION OF THE CHARGED POLYMER WITH MIXED MISCELLES OF CATIONIC AND NONIONIC SURFACTANT.
