Likewise, dont use any aldehyde-based odor killer. When added to a porto with an incompatible enzyme-based deodorant, the result is formaldehyde gas, which is very quickly lethal in an enclosed space.
Best advice: Piss in the fookin' bottle and close the top. Dump it in the AM and you are done. No need to get fancy. Its Burning Man. Nobody smells like a flower after 30 minutes in the dust. So deal with it.
