Joe, I may not be a true redneck, but I can jimmy rig darn near anything.... redneck baking soda blaster.... Air nozzle, small clear plastic hose. Cut slit in plastic hose, insert air nozzle tip into slit. Cut a 45 degree angle at the other end of the hose, stick it in a box of baking soda, hook up air nozzle to compressed air (I use 80-90 PSI), pull the trigger and let science do the rest....
