The handheld cleaning apparatus provides a handheld cleaning apparatus comprising a removable handle, abrasive particles, angled edges, open channels, and a flexible yet durable surface for scouring. The invention creates an abrasive, or “sanding,” cleaning apparatus that is better suited for cleaning dirty surfaces than a traditional cleaning sponge. The handheld cleaning apparatus retains the abrasive outer shell of a sanding sponge but is much more flexible and water permeable than current sanding sponges. To this end, the handheld cleaning apparatus comprises open channels, or “blow holes,” that promote water flow through the sponge and give the sponge flexibility. The size and the number of the channels vary by the material or density of the sponge. The handheld cleaning apparatus, additionally, contains a handle that is removably attached, which enables the consumer the ability to connect one or more cleaning apparatuses together to form the desired shape and form of the cleaning apparatus.
