The roll gap in a rolling stand for rolled strips is lubricated by feeding water via at least a first feed line and oil via at least a second feed line to at least one mixer, mixing the water and the oil in the mixer, feeding the mixture of water and oil to a sprayer, and spraying the mixture from the sprayer onto at least one work roll or backup roll of the rolling stand. To clean the roll gap hot water or steam is fed via at least one third feed line to one of the first and second feed lines or to the mixer at defined time intervals or as a function of a status of the rolling process while a roll of the rolling stand is being changed.
