A homemade device to clean fuel injectors from a gasoline engine.
Note, this can be dangerous, as the spraying cleaner can be flammable, as well as toxic. Do only in a well ventilated area with no ignition sources. Wear safety equipment such as safety glasses and gloves, a full face mask should be worn also in case the spray hits you. Wash with soap and water when finished the job, to remove any fuel injector cleaner from your hands.
