The shells are prepared in advance for washing without a trigger capsule, then they are poured into the tank together with ferromagnetic stainless steel needles and water with detergent for dishes, or commonly used detergents with a soapy base.

Started the engine, the needles are dragged into the liquid and exert a very effective mechanical cleaning action on the shells

The particular provision in the shape of a "altarpiece" of neo -nodimium magnets and the decentralization between the rotation center of the latter compared to the tank position (among other things also variable by hand), generates a "shaking" of the cartridges that facilitates it cleaning. Not only that, the arrangement of the magnets has been studied so that more types of tanks of various shapes and sizes can be used, up to the classic bucket ......... obviously without leaving the area delimited by the container support plate) the originality of These characteristics, unique in its kind in this type of products, to make a patent application.
