PURPOSE:To obtain an agent for metal washing liquors capable of suppressing the gelation of such washing liquors and of operating the relevant washing unit stably for a long time without declining in the detergency, containing a specific polyoxyethylene added-type ether-based surfactant. CONSTITUTION:This gelling-suppressive agent contains a polyoxyethylene-added type ether-based surfactant with a HLB of >=15, e.g. of the formula (R is a 6-12C alkylphenyl or a 8-16C alkyl; (n) is such a number that the HLB stands at >=15) such as lauryl alcohol-ethylene oxide (19mol-added) (HLB: 16.3). It is preferable that this agent be added to a washing liquor and a metal immersed therein and washed.
