My rats stink no matter what I do. Please help.

Hear me out, it’s not as bad as ferrets or a public restroom, but it definitely isn’t a pleasant smell 100% of the time.

I have two female rats and I have done all I can to make them smell less. I clean their soiled bedding out every day (they’re too old to litter train so I have no choice). I don’t throw it all away, just the pellets that expanded and turned to dust, and I spot clean high traffic areas and will just scoop out the bedding altogether from their pee corner. I use a cleaning deodorizing spray on their cage cimbing racks every day to clean off any pee and poops. I don’t know if I’m supposed to wash their hammock. They have two baskets as well that hang on the walls that I zip tied on and I don’t know if I’m supposed to clean those. I clean any solid hides, bowls, wood houses, etc. with the spray as well when I can and will hand wash the climbing tube since it has so many little grooves.

But no matter how often I clean, or clean everything, they always have a smell and I can’t get rid of it and people have told me that rats aren’t supposed to have a smell so I’m confused if I’m doing something wrong.

Please help me 😭
