  • the cleaning elements are preferably made from renewable BAW materials, such as cellulose or waste paper, which do not cause any environmental pollution.
  • the cleaning element softens due to the sufficiently long contact with water and it can be removed by simply rinsing the toilet without the risk of clogging internal pipes or the sewage system.
  • the sleeves 42 of the disposable cleaning elements 4 to 4 x shown in FIG. 5 preferably consist of a water-soluble, biodegradable material based on waste paper or cellulose.
  • the sleeve comprises an outer coating with increased hydrophobicity. This coating is also water-soluble, but the wettability compared to the inner sleeve material is reduced.
  • Such a biodegradable coating of the sleeve 42 can consist of biodegradable plastics, such as Ecoflex® from BASF. These statistical, aliphatic-aromatic copolyesters based on the monomers butanediol, adipic acid and terephthalic acid have properties similar to PE-LD due to their long-chain and branched structure.
  • biodegradable plastics can be extruded into films or tubes as well as used as coatings.
  • Other known biopolymers for example biodegradable materials (BAW) made from renewable raw materials based on starch, sugar or cellulose can also be used for the coating.

  • the coatings prevent the water from penetrating into the actual sleeve material during the short, only several seconds to a few minutes use of the cleaning element. As a result, this remains sufficiently dry and ensures the optimal clamping fit of the sleeve 42 on the extension 3, 83. As soon as the sleeve is cut open and away from the extension in the water, the inner sleeve material, which can be released very quickly, can be soaked by the water, so that the entire cleaning element can be easily disposed of via the sewage pipe.
  • the sleeve is made entirely of a biodegradable * plastic. The sleeve is no longer rigid, but an elastic tubular film. It does not dissolve due to brief contact with water, but can easily be washed away since no rigid areas can get stuck in the pipes.
  • the cushion 41 of the disposable cleaning element is preferably made of pressed BAW fiber material, also based on waste paper or cellulose, and glued or welded to the sleeve. If necessary, it can be equipped, in particular impregnated, with cleaning and / or disinfection-active substances which act in conjunction with water. Since only minimal amounts of preferably biodegradable or biologically harmless substances are used, environmental protection is also taken into account.
  • the simple construction of the holder according to the invention and the associated cleaning elements allows adaptations for different areas of application. Harder fibers are preferred for cleaning calcified areas, and it may be impregnated with a scouring additive. Cleaning after using the toilet and basic cleaning of the entire toilet bowl is preferably carried out with a softer pillow with any fragrance and / or disinfectant additives.
  • the entire surface of the holder can be cleaned, disinfected and dried with a cleaning cloth, which can be included with every disposable cleaning element.
  • This cleaning cloth is also in the Toilet bowl or disposed of in a trash can.
  • the almost to completely closed surface of the holder allows the holder to be cleaned very effectively and prevents internal dirt which can hardly be removed without dismantling the holder.
  • the excellent hygienic properties of the toilet cleaner according to the present invention enable alternative uses and areas of application in the household and sanitary area, such as washstands and bidets.
