OXO Good Grips Bottle Brush
With two types of bristles and a flexible neck, the bottle brush by Oxo is the ultimate weapon in cleaning skinny bottles and narrow jars. Because of the brush's flexible neck and rounded head, nooks and crannies are easy to get to and get clean. The nonslip handle stays firmly in place--even under running water--and absorbs pressure and tension away from hands.--Laurie Notaro
