An apparatus, method and kit for use in the treatment of substrates with a solid particulate material, said apparatus comprising a housing having mounted therein a rotatably mounted drum having an inner surface and an end wall and access means for introducing said substrates into said drum, the drum preferably having and elongate protrusion (1) located on said inner surface of said drum, wherein •(a) said drum comprises storage means for storage of said solid particulate material; and •(b) said drum comprises a first collecting flow path to facilitate flow of said solid particulate material from the interior of said drum to said storage means when said drum rotates in a first collecting direction, characterised in that said drum comprises a second collecting flow path to facilitate flow of said solid particulate material from the interior of said drum to said storage means when said drum rotates in a second collecting direction, wherein said second collecting direction is in the opposite rotational direction to said first collecting direction, and wherein said first collecting flow path and said second collecting flow path are different flow paths.

Apparatus and method for treating a substrate with solid particles

Aspects relate to a drum () for rotatably mounting in an apparatus for use in the treatment of substrates with a solid particulate material; a method of treating a substrate comprising agitating the substrate in a drum (); and a kit for converting an apparatus to comprise the drum (). The drum has an inner surface () and an end wall () and access means () for introducing said substrates into said drum, wherein said drum () comprises: &#x2022;(a) storage means () for storage of said solid particulate material, wherein at least part of said storage means is or comprises at least one cavity located in said end wall () of said drum (); and&#x2022;(c) a dispensing aperture () for dispensing solid particulate material from said storage means () into the interior of said drum (), wherein said dispensing aperture () is comprised in said end wall () of said drum, characterised in that said drum () comprises a valve () that is actuatable between a closed position and an open position, wherein when said valve () is in said closed position said solid particulate material is prevented from passing through said dispensing aperture () and when said valve () is in said open position said solid particulate material is permitted to pass through said dispensing aperture ().
