Put on your gloves and safety goggles to protect yourself from accidental sprays as you work.
Grip the small plastic nozzle at the top of the aerosol can. Pull it straight up and away from the can to remove it from the central tube.
Fill a small bowl with mineral spirits. Place the plastic nozzle into the mineral spirits and allow it to soak overnight. Scrub stubborn paint from crevices using an old toothbrush. Remove the nozzle and allow it to air-dry.
Pierce clogged paint at the tip of the central tube using a sewing needle.
Re-insert the nozzle onto the tube and depress it to make several test sprays.
