We spot clean each tub every couple of days wearing rubber gloves. As for our monthly clean, we take out the tub, dump the aspen, wash each tub with dawn soap and let air dry. Once dry, we use F10 and thoroughly spray the tub and let air dry. Once dry, add bedding, water cup, and snake. We also use disposable deli cups for water and each snake gets a new cup each week, sooner if it decides to "use" it for a toilet. Our snake facility generally has absolutely no smell. Good luck!
