Believe It Or Not
There are still plenty of abandoned estates/large buildings/laundries littered about the United States or Europe with mouldering equipment still in place. Am sure the scrap scavangers would love to get hold of the things but aside from wrenching the odd bits off you'll need a blow torch to otherwise take the things apart.
All this stuff was not only built for the duration but bolted and or otherwise built into the laundry area, so until the building is taken down they're not going anywhere. That is again unless someone goes in there with a blow torch! *LOL*
The old (and rather huge) ironer that was part of the Ellis Island hospital is still there. IIRC funds are being raised to restore that part of the island including perhaps the laundry area.
