Thanks for the replies! Yes I do rinse them off very thoroughly and no the soap is not for "smell good stuff", it's just the flavour of dish soap I have on hand right now. Glad to hear it won't hurt as long as it's washed off, I was worried for a second seeing that citrus is toxic to snakes. Thank you for the tip on using vinegar to clean bowls as well. I'm currently using white vinegar mixed with water when I spot clean my BP's enclosure.
