Resurectio!!
I am to blame for unearthing this thread.
So today I was working on a Raleigh that has quite a few steel parts with surface rust and a bit of deep rust in nicks and scrapes. The parts were dirty so I washed them before dipping them in OA or Evapo-Rust.
My usual wash routine is using a couple of different brushes, a rinse, and then a bath in one of the aforementioned products. This time, however, I used a ragged-out Scotch-Brite pad to wash the parts. Lo and behold; 80% of the rust was eliminated by the scrubbing!

This is the best (before) photo I have of the stem & bars. Both in the same state of rust. This is after the scrubbing and a 1 hour bath in mild OA. The scrubbing removed all but the rust in the nicks and scrapes.
