Odor Control in the RV
Home made #2 spray you do need to fill the toilet 1/2 to 2/3rds before spraying but does work and no need for air fresheners or vent running.

I have found the only time with an odor problem was when one or more of the vent fans were running. These units are pretty darned tight or ours is. Turn on the vent fan anywhere and you will get odors from the black tank when flushing. Most of the time we are buttoned up with the ac running. If cooking we open a vent and thee fan comes on but we open one of the screened windows a bit but still might not be enough.
