Eli5, why do destroyed tanks rust so quickly?

Question

Everytime you see footage of destroyed tanks and apcs they’re always rusted and broken down despite them being functional about a day ago not to mention no rain ever being present.

So, what causes them to rust so fast? Is it the heat from their destruction/explosion peeling off the paint or am I missing something?

Only thing that stops them from rusting is grease and coats of paint. When they are torn open the layers of unprotected metal layers will be directly exposed.
