Anytime my snakes relieve themselves I:

1. Empty the tub completely.
2. Wipe up anything in the tub I can with spraying
3. Spray the tub with Odoban and let sit for 5min (allows it to disinfect and soaks anything that dried to the tub so it can be wiped away)
4. Spend some quality time with the snake while I let the Odoban sit (IMPORTANT! )
5. Wipe down completely till all grossness is gone.
6. Change water, Odoban the bowl if needed.
7. Return everything to the tub, including the snake.

Then maybe once a month i do the scrub down. I use newspaper as a substrate which is why this works for me. with aspen or others this would be complicated and wasteful.
