Abstract
The stick swab has one or more compliant heads adapted for cleaning body orifices such as ear canals. The head or heads are formed with a contoured outer surface to aid in gripping and removing material or debris from the body orifices. The contours preferably take the form of a helical augur whereby material will be withdrawn from the orifice merely by appropriately rotating the swab about its axis.
