Abstract:
A method for providing a ready to use cleaning composition is provided. The method includes diluting a concentrate with water of dilution. The concentrate includes an anionic surfactant, an alkanolamine and a water hardness anti-precipitant mixture. The water hardness anti-precipitant mixture includes a maleic anhydride/olefin co-polymer and an EO-PO co-polymer. The EO-PO co-polymer having the formula: (EO)x(PO)y(EO)x (PO)y(EO)x(PO)y (PO)y(EO)x(PO)y(EO)x(PO)y EO is an ethylene oxide group, PO is a propylene oxide group, x is between about 10 to about 130 and y is between about 15 to about 70.
