Anyone have a good solution for removing chalky residue from dried Zerex G-05 coolant leaks? My thermostat housing gasket leaked and Zerex G-05 coolant 50/50 mix got sprayed everywhere by the radiator fan, love it. Just using water and a rag is not working to get rid of the dried on chalky residue. Something easy on the engine paint and body paint is needed. Would Simple Green or a solution of Cascade dishwashing detergent work? Any good solutions would be appreciated. Thanks!
