Short answer...not really. Had a very old timberline that someone put away wet. Stunk bad. Set it up outside and used a brush with laundry soap and scrubbed every square inch, then rinsed it several times with a hose. Left it set up outside for a couple of weeks afterward. When it was totally dry, I packed it up and put it away. When I set it up again, it still stunk, but not quite as bad. It has been retired, although I kept the poles.
