Here is my cleaning routine. Have using this routine for about a year now.

Remove snake and everything from the plastic tub. (printer paper, glass water bowl)
Rinse off the glass bowl in the sink.
Remove any debris in the tub.
Wipe down tub with bleach wipes (Walmart brand)
Dry up fluid with paper towel, wipe it down until mostly dry.
Let the tub dry for a few minutes.
Replace the paper and water bowl into the tub.
Put snake into tub.
Done.

Usually the pee and poo smell dissipates after the first bleach wipe down. If not then, it is usually gone after a day.
