For me its the old fans and vacuum cleaners. Over 40/years old each and still going strong. Clear labeling inside and have been fixed up multiple times.

    Not the OP, but you can clean all the parts when torn down for service. Vacuum bags instead of holding tanks also helps with that, but mostly it’s the filters. Replace all the filters and the smells go with it.
