The invention relates to an agent for cleaning interdental toothbrushes, said agent consisting of a first and a second kneadable and mouldable mass, the masses being used separately. Both masses have the same base composition. The composition comprises hydroxy propylated polygalactomannan and between 75 % by weight and 97 % by weight of bonded water and a liquid antiseptic solvent component, the first kneadable and mouldable mass containing predominantly sterilising active ingredients, whereas the second kneadable and mouldable mass contains disinfecting, antiseptic active ingredients for dental hygiene. The first kneadable and mouldable mass is designed to clean the interdental brush and collects solid particles that adhere to the brush. Said mass is also designed to sterilise the interdental brush, while the second kneadable and mouldable mass predominantly contains antiseptic agents which are applied to the brush before the latter is used or re-used. The invention also relates to a device for using the interdental brush cleaning agent. Said device consists of two separate containers that are held together and separately contain the first and second kneadable and mouldable mass. Each container preferably has a number of chambers and its own sealing cap, the lower part of which is provided with insertion openings (10), each of which communicates with one chamber (9). Both containers (2, 2) are held together with their bases facing each other by means of a clip-type retaining device (4).一種牙間刷清潔手段其包含分別使用的第一揉捏塑型組成物及第二揉捏塑型組成物被提出用以清潔牙間刷,前述兩種組成物都具有相同基本組成其包含氫丙基半乳甘露聚醣、75重量%至97重量%結合水、及液體防腐可溶成份,其中第一揉捏塑型組成物主要包含具有殺菌效果的活性成分,第二揉捏塑型組成物包含第二揉捏塑型組成物包含提供護牙的殺菌及防腐活化成份。第一揉捏組成物用以清潔牙間刷及移除黏著在牙間刷的固體顆粒,也用以對牙間刷殺菌。第二揉捏組成物主要包含防腐劑作為活性成份並用以在牙間刷的使用或再使用前調配活性成份。更進一步,一種使用牙間刷清潔手段的牙間刷清潔裝置也被提出,該裝置具有分離兩個容器收容在一起,每一個容器較佳地具有多重隔間,每一容器較佳地具有所屬封蓋可以封閉,容器底部提供插入開口(10),每一個插入開口與一個隔間(9)相通,兩個容器(2,2’)係藉由塑膠夾持部件將其中一個容器的底部面臨在另一個容器的底部的方式收容在一起。1‧‧‧裝置2,2’‧‧‧容器3,2’‧‧‧封蓋4‧‧‧夾持部件5‧‧‧水泡型包裝7‧‧‧牙間刷8‧‧‧側蓋9‧‧‧隔間10‧‧‧插入開口11‧‧‧鏡子
