Its worth noting that airfresheners and deodorizers only work three
ways. Some have an oil base that coat the particles with oil so they
cannot get airborne. Others have a strong deoderant that overpowers the
offensive odor with a different one. And a third kind have an
anesthetic that numbs your nose.

If you don't mind your raft smelling like a locker room or new car,
then use the second type: knockout is this type. If you don't mind your
entire sense of smell going by the wayside, then some Lysol or Bloo Goo
would do it. The problem with the first type is that, in a moving raft,
its VERY hard to keep the particles down...all that sloshing stirs it
up pretty well. First of all, never pee in the groover...that solves
some of the sloshing problem (as well as the fermentation bomb
problem). Ashes work well, but you have to toss in enough to coat the
top, each time, and eventually that adds up to several additional ammo
cans because of the bulk.

I haven't tried it, but I'd bet anything that a simple hand-pumped
pesticide sprayer with vegetable oil in it, mist-sprayed over the top
just before you box it up for the day would do it quite well.

But for the record, the anasthetic ones are the ones that work the
best. You know that's whats being used when someone gets on the groover
boat and says 'pyew! How can you stand this stench?" and then a minute
later says "hmmm, its actually not so noticable once you get used to
it."
