Re: Rust removal from steel component on the cheap.
With seriously rusted steel parts where mechanical cleaning is impractical i have used Hydrochloric Acid a couple of times. UK shop grade is generally 33%, i slowly added it to distilled water to get a more civilised 11%.
I do recall that a mixture of salt and vinegar often stinks to high heaven once it's been used to clean certain metals. It was enough to put me off!
