A paint preparation tool (10) having a distal brush head (18) with a mode valve to switch between continuous spraying under low pressure and pulsed spraying under higher pressure' connected by a hollow tube to a proximal remote control element (14) capable of switching off liquid to the brush head (18), or supplying liquid cleaner solution to the brush head (18) at low pressure or supplying liquid under the higher pressure to the brush head (18) using a rotary spool valve in the control element to actuate the mode valve in the brush head (18). The brush head (18) has bristles for cleaning and a pair of rotating rotors to provide the pulsed spraying under higher pressure.
