According to the invention, at least one of the cleaning chemicals used is a gaseous cleaning chemical. The invention also relates to a device for cleaning the barrel of a gun, comprising end blocks (1,8) sealably fittable to each end of the barrel and a reciprocable mechanical cleaning element to be placed in the barrel. According to the invention, the cleaning element comprises a core sleeve (21) of a size smaller than the barrel caliber and a brush part (20) of a size adapted to the barrel caliber and freely rotatably mounted around the core sleeve, and a reciprocatingly-moved drive means (5, 12, 17) passed through the aperture of the core sleeve and designed to fit the length of the barrel, the core sleeve (21) and/or brush part (20) being attached to said drive means.
