I found that if you remove a part from the acid and then leave it without thoroughly washing it down with water and/or turps, the acidic reaction continues and the next thing you see - on the less than robust bits (threaded bolts and studs) - is a crusty coating of rust
You are certainly correct in saying that careful attention to this process is required.
I will post the formula for this new acid wash when I have tested it
