I used to do a lot of car work. I had a modified classic firebird. You
would get hard to find parts at the bone yard and remove the rust
easily. The thing that I would use is sodium perchlorate (oxy-clean)
dissolved in water and a battery charger for electrolytic rust removal.
It was amazing, connect the electrodes, drop a part into a bucket of
solution, and in a day, the rust was gone. You can google for the exact
ratios and stuff.
I imagine you could construct a recirculating continuous stream system
with a water pump and a tray big enough to catch the return solution for
objects bigger than can be easily submerged.

What's your preferred product for chemical rust removal?
I've yet to try something that has really done the job satisfactorily.
Last product I tried was:
http://www.krudkutter.com/index.php?option=com_products&task=product&pid=17&Itemid=65
which is a remover and inhibitor. I found it did a poor job of removal,
and I'd prefer to have removal and inhibiting as two separate products,
as I often want one or the other, or want to do several courses of
removal first, and finish with an inhibitor.
I've also used rust converters, like:
http://www.amazon.com/Permatex-81773-Treatment-Filler-Compatible/dp/B000HBNX38/
on many occasions, and they work OK, but it's clearly an inhibitor and
not a removal product.
I've used "Naval Jelly" and similar products:
http://www.amazon.com/Henkel-553472-Loctite-Dissolver-16-Ounce/dp/B000C016OC/
which are advertised to be removers, but haven't been that impressed.
I see Krud Kutter has a formulation that is strictly a remover:
http://www.krudkutter.com/index.php?option=com_products&task=product&pid=18&Itemid=65
but I haven't tried it. I'm considering trying this next:
Evapo-Rust Rust Remover
http://www.amazon.com/Evapo-Rust-Rust-Remover-1-Qt/dp/B001BNZGY0/
which seems to have good reviews.
