Cleaning device and methods of manufacturing thereof
A cleaning sponge that efficiently utilizes melamine to effectively remove dirt and contaminants from a surface. The cleaning sponge includes a first sponge layer, a second sponge layer, a solidified detergent layer, a plurality of first pores, a plurality of second pores, and a plurality of third pores. The first sponge layer and the second sponge layer are connected to the solidified detergent layer on either side and provide protection for the solidified detergent layer against degradation. The plurality of first pores is distributed throughout the first sponge layer. The plurality of second pores is distributed throughout the second sponge layer. The plurality of third pores is distributed throughout the solidified detergent layer. The plurality of first pores and the plurality of second pores are in fluid communication with each other through the plurality of third pores. Water may flow through the cleaning sponge to create an effective surfactant.
