Don't make this mistake

There have been a lot of posts about holding tank odors on the forums recently. And wouldn't you know it I did a dumb thing that lead to holding tank odors. I recently went on an overnight excursion to an RV I like about 50 miles from home. I usually take the sewer hose cap off and leave the gate valves open when RV is stored and not used so the holding tanks can breath and thus eliminate tank odor. (Pretty neat trick and it works quite well.) But I Put my RV back in storage, must have been in a hurry, I forgot to open the gate valves and take the cap off, and when I went out to the RV yesterday it was filled with that wonderful holding tank smell. LOL!!! 😆 oops. Guess I learned my lesson this time. But I'd also like to learn what tip and tricks you guys use to keep holding tanks odors at bay when your RV is stored for long periods of non use.

Nothing. Once the tanks are emptied and cleaned ( I use Dawn ) , the valves are kept closed and never had an odor.

If it was summertime, the heat could have dried out your "P" trap(s). The odor could be from your grey tank. They can stink almost as bad as your black tank.

Also you need to keep the rubber seal on the toilet wet. The odor could come from a dry toilet ball valve too.

Drain, flush, 3 times. Close valves put mineral oil in all tanks to lube valves. Water and mineral oil or rv antifreeze in all traps (wont evaporate much). Never leave valves open except to drain and allow to dry unless you want critters setting up house. If you had odors your tanks weren't clean and your traps were dry. Black and Gray tanks should be washed with dawn and drained. Another trick is Ziploc bags with water in them over you sink and shower drains. In winter fill them with antifreeze.
