Abstract: A cleaning device is provided for use with a dip stick of the type normally found in internal combustion engines to measure the oil level. The device has a housing with an inner surface and a layer of absorbent material located thereon. The housing is shaped so that part of the dip stick can be laterally inserted within the housing in such a manner that the dip stick can be cleaned of excess fluid by pulling it longitudinally from the housing. The device has a magnet so that it can be mounted conveniently adjacent to the dip stick with which it will be used. Previously, various materials such as rags have been used to clean the dip stick while measuring a fluid level. This has not been satisfactory as a rag or suitable substitute was not readily available at all times and often the checking of the oil was over-looked.
