A method of cleaning a liquid fluid filter (2) by means of a at least one cleaning process (BW), wherein said cleaning process (BW) is started after a predeterminded time period of operation of the filter or a predetermined amount of liquid filtered, characterized by detecting a first transfilter pressure value (TMP) between both sides of the filter (2) at a first point in time and detecting a second transfilter pressure value (TMP) between both sides of the filter (2) at a second point in time, calculating a difference value (”TMP1, ”TMP2) of the two detected transfilter pressure values (TMP), comparing said difference value (”TMP1, ”TMP2) with a limit value XX, decreasing said predetermined time period or said predetermined amount of liquid to be filtered between two starts of said cleaning process BW if said limit value XX is exceeded by said difference value (”TMP1, ”TMP2). |
