Help!
I'm trying to remove the chrome-plated nut that holds the wiper wheelbox
to the car. The bushing it threads onto (part of the wheelbox) turns
when I turn the nut. Yup, there's corrosion in the threads. But it's not
your Standard Triumph rust. The bushing is non-ferrous (pot metal?). The
nut is chrome plate over brass.
Does anybody know what kind of alien chemistry I'm dealing with? More to
the point, what do I soak it in to loosen the nut? 3 good soakings in
'Snap Rust Buster' haven't budged it, but hey, it's not rust!
This is a replacement wheelbox - I cut the nut off the trashed original
to get it out of the car. Immersion IS an option. But in what?
