You never Know what your gonna find. Yes that is a dollar bill you are seeing. Today marks the first time I have ever encountered laundered money in a dryer vent line. I have found pens, pencils, coins, buttons but never paper money. The homeowner called and said " I've replaced the thermostat twice and my clothes are still taking two cycles to dry". Well the answer to her problem wasn't the two thermostats, it was a thorough dryer vent cleaning by All Clean, LLC. We both got a good laugh when we saw the dollar bills embedded in the lint. The lint you are seeing is a solid 4" diameter lint tube. Also this is only part of the lint that I pulled out of the 4" vent line. If you or anybody you know has noticed your clothes taken more than 5omin to dry, you need to clean your dryer vent. Luckily the homeowner didn't have a fire.
