It's amazing that a toilet could even be engineered with that seeming design flaw, a real oversight. If you could seep antibacterial cleaner (no bleach) past that seal, that could counteract odors emanating from that hidden area until you replaced the seal.
As an aerospace safety/environmental manager, I can relay a phrase from my industry: "Dilution is the solution to pollution." True for liquids, solids, gases. So yes, more water, along with blackwater chemicals, can help, although it can be tough to conquer odors when it's truly hot outside. And an effective toilet "flush" can be just a film of water rather than a bowl surge. After use I briefly spray the entire toilet bowl with a generic household cleaner, which effectively rinses (and also detergent-soaks) the entirely of the toilet interior. Therefore no surface odors. I also do a "hillbilly tank flush" when draining. Drain blackwater, close valve, dump two buckets (7 gal) freshwater down toilet, drain again. You can see the effect by watching the clear elbow in the drain hose.
But the problem is the seepage from the bowl that gets into the space between the outer and inner bowl. No dilution is going to happen there. It's gonna seep in there to some degree no matter what due to the flawed design. And the only way to for it to be discharged is to remove the toilet, carry it outside(vertically) and dump it....my conclusion is this: The toilet is a piece of junk and needs to be replaced........so I did.
