I house my male Syrian hamster in a tank which I clean every week. I take it in the bathtub and scrub with a sponge and dishwashing detergent, then rinse it off. No matter how many times I soap and scrub however, the stench of hamster urine still lingers! The tank can be sparkling but the smell just won't go away. How can I clean it efficiently and get rid of the pee odor?
I've heard bleach works but won't that irritate my hamster's nose?
