Use Evaporust or even agricultural molasses. Both work well.
That's why I said to look on youtube for instructions, they tell you to keep an eye on it. It's 5% acid so the "soak and forget" mindset is something you shouldn't have.

Sorry, but it does a better job than anything else other than media blasting.

One could also look on youtube on removing rust through electrolysis if you want to "soak and forget" it.

ALSO, on youtube, there are a slew of videos doing rust removal comparison test. I'd advise having a look there first so you can see your options. Should be enough information to help you in not wasting time and money on stuff that doesn't work or barely works.
