A downhole cleaning tool ( 10 ) for oil mind gas wells. Brushes, scraper, wipers ( 32 ) and the like are mounted on a sleeve ( 14 ) over a tubular body ( 12 ), and the members successively moved towards and away from an inner surface of a tubular to be cleaned. Movement is created by a jarring action on the tool with the sleeve traveling over undulating profiles ( 26 ) on the body to actuate the cleaning members. The tool may be deployed on a slickline or wireline.
