From a friend . . .
If your dryer connection (the tube between the dryer and outside) is clogged, a leaf blower can be a simple and elegant solution.
If you choose to try this, DO NOT do it from the outside in. You will clean out the lint blockage by coating everything within 30 feet of your laundry room in a coat of finely powdered lint which will require multiple vacuumings/dustings to get out.
