I don’t deep clean and barely clean at all if I’m being honest. I’m a strong believer in natural fauna/flora(bioactive) ecosystems and all of my chameleons have lived long lives so far. None of them have had any issues relating to enclosure cleanliness. I wonder if anyone ever has with the exception of reinfection from parasites

. Of course that’s anecdotal…
IMO sterilizing is only useful when there is a known pathogen you’re trying to eliminate. Otherwise, my feeling is that you are just wiping out harmless bacteria, which often outcompete dangerous bacteria/fungi/etc. Once again IMO(I’m going to use a lot of *my opinion’s* in this post

)best case scenario you’re just wasting time.
If I have mold I sometimes bury it in the soil or leave it if it’s just new enclosure cycling. Poop gets cleaned up by CuC or buried if no established CuC yet. The only thing I might do is break off a leaf with poop on it or wipe down the walls for viewing purposes.
I also have a giant Caribbean land crab which is more sensitive to environmental issues than a chameleon IME. I keep him the same way(bioactive, bury old food, etc) and he’s been thriving for over a year now.
I clean stuff up in my own house(as much as I can with kids heh), keep it tidy, etc, but I don’t sterilize things constantly and for no reason. Doesn’t do our immune systems any favors IMO. I treat my animals the same. We’re all going strong.
I want to add if there’s risk for parasite reinfection, wild caught quarantine, babies you’re keeping an eye on, etc then of course it makes sense to lock down the enclosure and sterilize a little more. I feel it should just be deliberate with purpose.
