I have a lot of spare tubs so when cleaning I just swap out tubs and if I run out I clean what I need on the spot and if I do not need any clean tubs I clean them when I am done with diluted bleach. Usually I only have to change paper but if there is a mess on the tub its self then I will swap it out. I also keep one empty tub per a rack so I just have to move the snake up to the clean one and change paper and keep moving. Water bowls I have 2 for each tub. One in use and one clean ready for use when I change water they get run through the dishwasher and set aside for the next water change. In all it takes me about 2 hours to do one full cleaning of all the snakes. I also schedule mine so I do babies one day and adults another day. That just makes it easier for me in the end.
