The bathtub itself was easy to clean, I just ran the shower for a bit and it all washed away! But I had to get out to check some stuff and tracked batter all over the floor and walls, that took an hour or two of scrubbing to get off LOL But brownie batter is amazing, it's slick and goopy and you can feel it slowly drip down all over your body. It's super squishy and coats you in a nice shiny film!
