When I leave the windows up for extended periods, there will be a vague,
unpleasant smell. Almost dog poop, but not quite.

I have tried leaving it open for long periods, but that only remedies
the problem temporarily. Left a few dryer sheets in there to soak it up,
but still just a short-term fix.

Any ideas on a way to permanently remove pesky odors?

Thanks,
