The first surfactant has the general formula: R—O-(A)H. Ris an aliphatic hydrocarbon having from 8 to 11 carbon atoms, A is an alkyleneoxy group having from 2 to 5 carbon atoms, and m is a positive number. The second surfactant has the general formula: R—O-(B)H. Ris an aliphatic hydrocarbon having from 12 to 14 carbon atoms, B is an alkyleneoxy group having from 2 to 5 carbon atoms, and n is a positive number. The polyalkylene glycol is present in an amount of from 3 to 20 parts by weight. The method also includes providing a rinse formulation, applying the cleaning formulation to the surface, and applying the rinse formulation to the surface.
