As I understand the logic, many things are so radioactive that you can't move them. Most water is contaminated so you can't use precious clean water for bathing, so most people and scenes would be dirt-caked from just dry washing.

Also continuing my riff – look at the VFX set pieces. They're all golden sunshine back lit with glorious sunsets. Roger Deakins gets into this gripe a lot on his podcast and I agree with the sentiment: the VFX tries to add too much beauty to images because they can. They shouldn't though, they assist the looks in ways what support the nature of the story.

These shots are too lit ie using obvious big soft source lights to make everything nice and controlled-looking, augmented by beauty-centric VFX tendencies, and the makeup and vanities teams aren't muddling up enough of the image.

Finishing / color grading may yet be done to unify the looks and add some grit with more grain, halation and blurring, but the vast majority of those elements should be done on set and in-camera. They have the resources for it.
