The invention is a disposable dust pan. It is stored as a flat sheet in a stack ready for use. When needed, one sheet is peeled away from the stack and folded to form a convenient dust pan. Non-hardening adhesive is used to hold the sheet in the folded orientation and to seal one edge to the surface requiring cleaning. After use, the dust pan is sealed to trap dust and debris within a folded pocket and then the entire device is discarded.
