Abstract
A squeegee has a handle consisting of a straight elongate cylindrical member having a pair of elongate blades mounted along one side, flush with one end of the handle and protruding beyond the opposite end. The blades each have a rigid base portion received in one of a pair of channels and a flexible distal portion protruding therefrom for wiping a surface. The blades are integrally formed in a shallow S-shaped cross section and the channels are formed with parallel curved sidewalls conforming to the curvature of a portion of the width of the blade.
