Nope. Only happens when changeing to Northern. Mist is presumably fine oil
particles.
BTW, talking of such aerosol effects, anyone know what happened when
experiments carried out on tube with spreading microbes, back in 1950s?

Surely you remember "Quatermass and the Pit"?

If it clings more to magnetic surfaces, why don't they install more
magnetic surfaces to remove it from the air?

My vote has to be the Northern Line, every time I travel on that line I
always have black 'dirt' in my nose.. no its not bogey/snot!

Agreed! not only does the problem of "black dirt" seem worst on this
line (I tend to experience it on most lines if I travel long enough),
but I also feel like passing out when on the underground part of the
line between Camden Town and Golders Green.

Given that others I've spoken with also feel the same along the same
part of the line suggests to me that the are is aweful there.

It's true. I always feel lethargic on that part of the Northern Line -
especially between Hampstead and GG. I've often wondered if it was just me
or if outside factors played a part.
