Description

[Detailed Description of the Invention] The present invention relates to an improvement in a cleaning tool for wiping off dirt adhering to a cleaning surface.

Conventionally, when cleaning window glass, show windows, mirrors, etc., when there is slight dirt, a cleaning surface is sprayed or applied to the surface to be cleaned, and the cleaning solution containing the dirt is wiped off with an absorbent cloth or paper. Alternatively, a cleaning method is known in which dirt is removed from the cleaning surface by wiping it with a rubber wiper.

In addition, if the dirt is firmly attached to the surface to be cleaned, use a relatively flexible and frictional cleaning tool such as a nylon non-woven cloth or sponge impregnated with the cleaning solution after softening the dirt by spraying or applying the cleaning solution directly to the dirt. After polishing while softening the dirt, the dirt on the surface to be cleaned is removed by wiping it with an absorbent cloth or paper, or by wiping it with a rubber wiper.

However, wiping off the cleaning solution containing dirt with this water-absorbent cloth or paper requires a large amount of cloth or paper, and it takes a lot of effort to polish and clean the dirt with a cleaning tool that has frictional force. It takes a lot of effort and time.

Furthermore, wiping off dirt-containing cleaning fluid with a rubber wiper is quick and easy, but the dirty cleaning fluid may flow down the cleaning surface, staining the cleaner's hands and clothes, or leaving the corners of the cleaning surface. If the cleaning liquid accumulates on the cleaning surface or drips from the edge of the cleaning surface, it is necessary to wipe it off again with an absorbent cloth or paper.

The present invention is an improvement on this, and aims to provide a cleaning tool that can wipe off all kinds of dirt adhering to the cleaning surface together with a cleaning liquid sprayed or applied onto the dirt.

In order to achieve this purpose, the present applicant has proposed this cleaning tool in U.S. Pat.
