where R is an alkyl group having 1 to 4 carbon atoms or a phenyl group, and n is a number of from 1 to 5; and (b) at least one cationic surfactant, where the weight ratio of (a) to (b) is from 8:1 and 100:1, and where the cleaning agent concentrate comprises less than 0.1 percent by weight of fatty alcohol alkoxylates, amphoteric surfactants, or mixtures thereof. When diluted to 0.5 to 5% by weight with water, a cleaning agent is formed that is low-foaming. The cleaning agent is especially useful for cleaning and passivating metal surfaces using a spray application.
