Abstract: An in-toilet dissolvable cleaning tablet holder which comprises a basket structured to contain the cleaning tablet. The basket is characterized by a bottom surface and at least one side wall, each incorporating aperture cutouts to allow contact between the tablet and the toilet bowl water. The basket is connected to an arm mechanism, which is configured for attachment to the rim of a toilet. The positioning of the aperture cutouts is such that, upon installation, the perimeter of at least one of the cutouts comes into contact with the toilet bowl.
