Was just reading up on some home tips etc., and wondered whether it would hurt anything to put baking soda down the toilet to help with odor? We have tried numerous brands of chemicals, and nothing works well. Just to be clear, we are FT'ing, workamping, and we leave our grey tanks open, but black closed.
Thanks in advance!

Shut off the water and open the toilet valve and look down there. We had a lot of accumulated `dirt' just below the toilet and above the tank. Took a brush to it and the dirt and smell went away.
Ditto the bathroom sink had some accumulated `stuff' just below the drain which smells a lot better since we cleaned it out also.

I can't speak to baking soda in RV tanks (we don't use any chemicals in our RV tanks and don't seem to have any issues).
However, I can address smaller holding tanks used for multi-day river trips. Baking soda is perfect. There are almost no odors, even during week long hot weather trips. Big difference though is there is no (or very little) fluid in river toilets (we urinate in the river or on wet ground....as per most river management agency rules and we don't add any additional water until the last day prior to dumping). So I am not sure if the baking soda wouldn't be diluted too much by the water in the black tank. Hey, it can't hurt to try though.
Maybe the best solution is to figure out why you are getting odors in the first place. Perhaps a larger, or higher, vent would help?
Other than a brief whiff when flushing toilet (especially if any fan is exhausting) you should have NO odors from waste tanks (black or grey) if system is working properly ie:
Water is in toilet bowl (vapor barrier)
Toilet floor flange is good (mechanical barrier)
Sink/shower 'P' traps hold water (vapor barrier)
Air admittance valves open/close correctly (located on grey waste drain lines to prevent 'P' traps from being sucked dry when draining grey tanks....located under sinks...if not closing odors from grey tank can come back into RV)
Waste tank vents are free & clear....properly venting above roof line
Washing machine (if plumbed for one)..'P' trap holding water
Water is the key.......flushing toilet, draining tanks (high level to flush & carry solids out), rinsing tanks.
Is it time for your medication or mine?

Baking Soda is a great scouring powder for hard plastic surfaces. It works wonderful for ice chests / coolers / refrigerator interiors and especially the rubber seals around a refrigerator. It's consumable, so it won't hurt or contaminate or poison you or pet. It's also a deodorizer. But depending upon the item, it could take a lot. An RV holding tank would probably take a lot. However, if the tank was empty and you added a couple gallons of water and a box of Arm and Hammer down the toilet, then go drive around and let it all slosh around, it will probably do a pretty good job of eliminating odors. And you won't have to dump it either.
Baking Soda works pretty good on cat litter to eliminate odors and extend the life of cat litter. It's used in washing machines to help eliminate odors and boost washing power. So, yes, it will work in your black tank, if you make it strong enough to cover the space.
And did I mention, it makes a really great scouring powder on surfaces that touch food?
You really need to think in terms of what is the ultimate extreme usage you'll be experiencing with your truck, not what is the lightest usage and hope it's OK when the extreme happens. - I quote myself.
The best thing I found for controling tank odor is to always travel with a 1/3 of a tank of water, sometimes we add some Dishwasher soap and calgon to help in cleaning, it's the sloshing around of the water while you travel that really goes a long way in keeping tanks clean. Quite often we drain the tanks when we arrive at our next destination, then add about 5 gallons to the black tank before using.
