The curved brush can reach every area of the bottle including the shoulder, the most difficult place to clean. The brush will not scratch the glass and is an excellent tool for cleaning heavily soiled vessels before placing them in a laboratory glass washer. The uniquely designed swivel head fits through any neck with a diameter of 24mm or more. The natural bristle brush, mounted in a 1-3/4" wooden back, swivels on a plated metal rod attached to a 13" long hardwood handle.
