I have a poly hulled, Necky Alsek with fore & aft bulkheads and storage spaces which hermeticaly seal. In warm weather, even when freshly washed out with soap and rinsed, as soon as I close the hatches, after a few hours there's a nasty smell when I open them up again. I tried washing them out with soap and water, a few ounces of mouthwash dropped in before closing the hatches, but nothing seems to really work well.
--Anybody have any ideas?
--Also, I'm worried about damaging the material used to glue the bulkheads in place if I try some exotic kind of anti-bacterial/anti-fungal chemicals --- are these concerns unfounded?
