ABSTRACT:
The present invention provides automotive cooling system cleaning formulations suitable for addition to antifreeze/coolant systems. The cleaning compositions use a mixture of a metal cleaning compound such as EDTA, polymeric polycarboxylates and alkoxylated alcohol based nonionic surfactants to provide rapid cleaning of the coolant system. The cleaning formulation is then removed from the cooling system.
