I just thought about it when rebuilding the rear brakes on my sons truck. I had a partial full quart bottle of ATF, so I dumped in an equal amount of acetone and gave it a shake. I just dribbled it on the castanets I needed to remove and it seemed to do the trick. What could be easier or cheaper?

I had such good luck I keep it in a
pump oil can all the time, & add a little acetone if it's been
sitting a long time between uses.
Did you use the old petro based ATF? That's what I used. I never
saw anything about which blend to use, so I used what I had on
hand. I save the synthetic ATF for my RV-4 brake lines. :-)

Your results may vary, I did not have that good of

it works, I’ll try again.

Actually, I can't speak to the chemistry of mixing the
two, but if you put an equal quantity of each in a pumper
oil can, shake it up, and squirt it on solidly rusted
bolts/nuts & let it sit for a while, they *will*
magically loosen with much less force than you would
expect.
I used the technique on a Massey Ferguson tractor that
hadn't been apart since the early '60s, & was amazed
at how well it worked.
But no reason to take my word for it; for less than $10
(or maybe nothing, depending on how well your shop is
equipped), you can check the 'science' for yourself. :-)
