ABSTRACT:
A smooth-surfaced, firm, and flexibly bendable elongate element has a clog-snagging end portion which is provided at least one clog-snagging outwardly extended clog-snagging element. The clog-snagging portion is forcibly inserted through a drain hole into a water trap in which a fibrous clog has formed and is to be removed. A portion of the elongate element outside the water trap is flexibly shaped into a crank shape by the hands of the user, and is manually rotated to cause engagement between the clog-snagging element and twisting thereon of fibrous material contained in the clog. Upon such engagement, the elongate element is forcibly withdrawn from the drain hole with a portion of the clog detached from the water trap and engaged thereto.
