Why do plastic cat litter boxes hold onto smells?

Plastic litter boxes absorb and retain foul urine odors over time that cannot be scrubbed out, leaving homes smelling terrible within a single day. Cat owners are left desperate for a trustworthy metal alternative because standard plastic boxes trap smells permanently no matter how clean they are kept.

I currently use the Tidy Cats Breeze system and I love it EXCEPT for the fact that the box itself is plastic and holds onto smell.source ↗

I’m looking for a metal version of the box, but the only ones I can find are on AliExpress or Temu which I don’t really trust.source ↗

I have two adult neutered cats, but we just can't get them to stop peeing everywhere, even though their litter boxes are always kept clean!source ↗

it is completely impossible to keep the place smelling decent. Seriously, the good smell doesn't even last a single day, and I am about to pull my hair out from exhaustion!source ↗

I have no idea where the cat pee has soaked in or what to do to get rid of it for good. I’m desperate, please help!source ↗
