Undiluted white vinegar is the best thing for hoses...it not only
reduces odor, but also dissolves sea water minerals. And won't hurt the
toilet or the hoses.

However, it's your boat, Gordon...I can only advise and pass on what
I've learned over the last 20 years.

Don't see how nasties are going to wake up if everything is totally dry?

Spores.

Spores need water to germinate. That's the whole point of my comment. If
everything is bone dry they are going to remain dormant no matter how warm
things get. If you smell anything its from decomposition not growth.

As for 10% bleach damaging hoses, I suppose a very thin layer of hose might
be degraded but hoses are pretty thick. If you have any kind of scum inside
the hose the bleach will attack that before it gets to the hose. After a
few days all the oxidizing power of the bleach is lost and you've basically
got a weak solution of sodium chloride.
By the way, when I suggest 10% bleach I mean a 10% dilution of household
bleach.
Household bleach is about 5% sodium hypochlorite so 10% gives you a 0.5%
final solution. That's 1 gallon of household bleach to 9 gallons of water.
I think there are more concentrated solutions of sodium or calcium
hypochlorite available for "super chlorinating" swimming pools and water
supply systems. You don't want to use these.
