Well it's been another average night in the life of a commercial grease duct cleaner, tonight we cleaned several hundred feet of horizontal duct in a hospital cafeteria and yes, you guessed it, our tool and the very job we have in mind for Mike was putting a man in the duct that measured 10" X 20". This is a very dirty job and we wonder if Mike has the stuff to brave a horizontal scramble in the windy city. Maybe Mike has what it takes to take a ride in a bosens chair in a vertical duct, the next big one we have planned is 26 story descent. Give us your thoughts fans and tell us if you think this is one dirty job Mike should check out.
