Nice thread of the whole crew together! I really like the takeout container-turned-hide you've got with the carpets. I might just have to try that myself -- I've certainly got enough old takeout containers laying around here!
I do full cage cleanings seasonally, so roughly every 3-4 months. Scrub down and clean all the décor that can be, scoop and vacuum out all the old substrate, clean and scrub all the other surfaces in the enclosure with Healthy Habitat, and add fresh substrate and cleaned décor. I typically re-arrange the décor layout in the enclosure after cleaning as a little bit of passive enrichment. Since F10 is some pretty powerful stuff, I typically only use it if I'm cleaning after someone was sick or if I'm cleaning an old enclosure for a new arrival (ie. a pre-quarantine super deep clean).
This reminds me -- it's actually time for the longi's seasonal cleaning. Time to start chipping away at that Reptichip block that just arrived!
