A retractable bristle brush has a handle with a stem attached at one end thereof to one end of the handle and extending longitudinally therefrom. A cylindrical barrel extends concentrically around the stem and has a plurality of spaced holes therethrough. A plurality of bristles is affixed at one end to the stem and project at their other end through the holes in the barrel. An actuator is connected with one of the barrel and stem to move the barrel and stem relative to one another to deflect the bristles and cause them to retract through the holes to a shielded position inside the barrel. The natural resiliency and memory of the bristles causes them to move the barrel and stem relative to one another to their original position with the bristles extended through the holes when pressure is released from the actuator.
