i cleaned up an apartment post fire of a horder whos place looked like this. everything was coated in a icky paste of burned plastic. i was told i could keep anything i found, i looked to see if he had anything valuable but couldnt find anything. he was a photographic painter of some kind, had a couple dozen wildlife paintings that were pretty good but reeked of burned plastic/smoke so i threw them out too. took like 3-4 days of hauling stuff outside and throwing it one of those big bins you see at the dump.
