We.re restoring a 41 chev and want to reuse the original seat frames. the springs are still in decent shape aside from a hefty layer of surface rust and LOTS of critter nesting.
Do folks have any luck getting heavy diesel machine shops to take these things in and run them through their high pressure rotory spray hot tank booths to clean them up, or is there a better way? I cant imagine trying to sandblast the things with all those little coils, aside from taking an eternity , i'd be concerned there might not be much left after.

You haven't gotten any answers to your question, so I'll tell you what I do with old seat springs. I generally just scuff them up with a wire brush and spray them with Loctite Extend. That just keeps them from getting rustier, which is really all you need. The original springs probably didn't have any coating on them. The main thing is to get rid of all the cotton and burlap which are the favorite nesting materials of every rodent in the world. Check out this thread: Re-padding an old car seat.
