This is the best flexible hose to use, where you need to connect the
rigid if you use it: http://www.aussieglobe.com/avs96.htm. This is what
Sealand used to sell as Odorsafe, but they supply something else now
that doesn't work as well and is more expensive. As far as getting rid
of the current odors, a good scrubbing with simple green or any good
cleaner works great. If that fails, PureAyre odor eliminator seems to
work great. http://www.pureayre.com. No commercial connection, just a
satisfied user.
