I had to work on our kitchen stove tonight, and made a huge mess in the process. Cleaning up with the ash vac after it was all over, I glanced over at our 18-year old refrigerator, then looked at the PowerSmith, and thought "HEY, I can use that little tube attachment to get those coils cleaner than they've been in years. In about three minutes, I cleaned out a huge amount of dust that I've never been able to reach before. Currently drinking a colder-than-usual beer, and enjoying the warmth of my newly-installed 18-year old pellet stove!
