<p>The present invention forms multiple cleaning areas/surfaces so that they are piled up in layers, and the sewn part is formed so that it fold with the central part. When the cleaning area/surface and other side of cleaning are contaminated with dust, the re-use based on the fold of the other side of cleaning area/surface with the cleaning area/surface, centered on sewn part. Thus, the inconvenience of having to cleanse frequently is mitigated. Moreover, time needed for cleaning is reduced since the frequency of cleaning is reduced. Moreover, rough cleaning area/surfaces such as a pot cleaner are injected into the center of the cleaning area/surface to remove the dust and alien substances that are otherwise not removable using regular cleaning area/surface.</p> |
